The cast of actors can make or break a movie. It’s all well and good having a fantastic script, but if the actors can’t convey the required emotions, it’s likely you’ll find the project dead in the water. It would also be naive to deny that actors with acertain level of star powerare going to be bigger draws and entice more viewers to the movie. Obviously, it’s not the only contributing factor to amovie or franchise’s success, but it certainly helps.

Regardless of the motive — whether to utilize the actors’ star power or if they’re genuinely the best for the role, or both —assembling impressive casts of A-listersis nothing new in Hollywood. Perfect examples of such can be seen if we look back to the days of The Rat Pack, which saw the likes of Frank Sinatra, Dean Martin, and Sammy Davis Jr, among others, appearing in multiple movies together or to theGreat Escapewhich starred megastars Steve McQueen, Richard Attenborough, and Charles Bronson.

Below is a list of 10 movies that feature the most impressive casts ever assembled. (Please note: despite pretty much every actor active at the time appearing in it,Movie 43has been omitted from the list, because it’s hard to justify its existence as an actual feature film).

13The Departed

The Departedis a fine film. One of the greatest ever, in fact, and remains to datelegendary director Martin Scorsese’s only Oscar win for Best Director. It also won Best Picture, Best Adapted Screenplay, and Best Film Editing. Aside from a brilliant director and script, it also benefits from a fabulous cast.

The brash Boston-based gangster romp saw a number of actors on the cusp of legendary status, including Matt Damon, Mark Wahlberg, and Leonardo DiCaprio, sharing the screen with true icons of cinema like Jack Nicholson, Martin Sheen, and Ray Winston. Featuring Scorsese’s trademark violence, rocking soundtrack, and epic, twisting plot,The Departedis a movie that works on so many levels and deserves all the success it achieved.

12Tropic Thunder

Tropic Thunderreceived numerous accolades, including an Oscar nod for Robert Downey Jr.’s performance and Golden Globe nominations for both him and Tom Cruise. It has also gone down as one of the most controversial movies of all time as well, with some findingDowney Jr.’s use of blackface, Ben Stiller’s portrayal of the mentally handicapped, and Cruise’s overly stereotyped Jewish character, particularly offensive and insensitive.

Controversy aside, the premise is certainly intriguing. It follows a group of actors, who, while shooting a Vietnam War film in a jungle, encounter real danger and have to rely on what they’ve learned from acting to survive. In essence, the movie acts as a parody of the Vietnam War epic of the past. The movie also features what is probably the greatest cast ever put together for a comedy movie,including Jack Black, Ben Stiller, Robert Downey Jr., Tom Cruise, Steve Coogan, Bill Hader, Matthew McConaughey, Danny McBride, Nick Nolte, and more celebrity cameos than you could shake a stick at.

11Shark Tale

DreamWorks Animation movieshave a long history of compiling huge casts of Hollywood mega stars to lend their voices to its animations in order to give them that extra character. Most of the time, it tends to pay off as they’ve developed a strong reputation for creating some of the most enjoyable and financially successful animated movies in the business. Although it’s not always the case,Shark Talefeatures what is arguably their most impressive cast, yet it was met with lukewarm reactions from fans and critics alike.

Will Smith plays the entrepreneurial lead shark, Oscar. Alongside Smith were two of Hollywood’s most sought-after leading ladies at the time, Renée Zellweger and Angelina Jolie. It also stars Jack Black, Robert DeNiro, Martin Scorsese, Ziggy Marley, and Doug E Fresh, as well as musical cameos from Christina Aguilera and Missy Elliot.

10A Street Cat Named Bob

A Street Cat Named Bobis based upon the true story of Bob and his friend, James Bowen, played by Luke Treadaway in the film. It’s a touching tale about finding hope and redemption through love. The human cast did a wonderful job of respecting their real-life counterparts and bringing them to life on screen.

However, the true star of the cast was Bob the cat, playing himself.

9Role Models

Role Modelsis a raunchy comedy filled with non-stop laughs. When two friends, Danny (Paul Rudd) and Wheeler (Seann William Scott), get into trouble, they are given the choice to go to jail or participate in a community program where they have to be role models for troubled kids. The premise promises enough comedic moments on its own, but the cast plays off of each other and the circumstances to add a ton of charm to the movie. Not only do Rudd and Scott’s performance styles complement each other perfectly, but they each made a connection with their younger co-stars, Christopher Mintz-Plasse and Bobb’e J. Thompson.

With other great comedians working beside them, like Jane Lynch and Ken Jeong, it is hard not to laugh the whole way through.

Plus, Paul Rudd isalways a treat to watchon his own, so how could this cast fail?

8The Lord of the Rings: The Return of the King

When it comes to a cast of pure talent and industry legendsThe Lord of the Ringsis rivaled only byThe Harry Potter Series.The Return of the Kingbrings together the likes of Ian McKellen, Sean Bean, Viggo Mortensen, Christopher Lee and casts them alongside a slew of talented young actors on the cusp of superstardom, including Elijah Wood, Orlando Bloom, and Liv Tyler.

7The Devil All The Time

Although it is easy to miss this Netflix drama,TheDevil All The Timeis a dynamic and suspenseful filmworth watching. The structure of the film is unique to most other films, as the dark secrets of several seemingly unrelated strangers come to a head in a twist finale. While the writing and directing is clever and fantastic, the cast elevates the material to make every character, no matter how small the role, intriguing and fun to watch.

For those who only know Robert Pattinson from movies like theTwilightsaga, this film is the perfect example of how great an actor he is, and how he has so much more range than just playing a grumpy teenage vampire. InThe Devil All The Time, he plays a snobbish Tennessee preacher with an unholy secret life. In a scene between him and leading man Tom Holland, the two British actors play off of each other perfectly. Their subtle acting choices and fierce concentration on each other take a scene that is already tense and transform it into a heart-racing showdown. The cast is filled with other stars that completely dedicate themselves to their roles, like Sebastian Stan (Marvelfranchise,Black Swan), Bill Skarsgård (It,John Wick), Harry Melling (Harry Potterfranchise,The Queen’s Gambit), and Mia Wasikowska (Crimson Peak, Alice in Wonderland).

6Ocean’s Twelve

The originalOcean’s Elevenfeatured an impressive ensemble cast starring some of the biggest names of the time, including Frank Sinatra, Dean Martin, and Sammy Davis Jr. The sharp and stylistic 2001remake from Steven Soderberghblew our collective minds by managing to assemble the most impressive (and glamorous) cast of A-listers Hollywood had ever seen consisting of George Clooney, Brad Pitt, Matt Damon, Don Cheadle, Andy García, Bernie Mac, Casey Affleck and Julia Roberts.

The sequelOcean’s Twelvemanaged to retain the cast and the fun and energy of the original, and turn it up to, well, 12. Catherine Zeta-Jones joined the main ensemble along with Eddie Izzard in a supporting role. There were also cameos from Topher Grace, Robbie Coltrane, and Bruce Willis himself.

5The Outsiders

This iconic coming-of-age drama directed by Francis Ford Coppola boasts one of the finest casts of all time. What makesThe Outsidersspecial is, at the time of its release, none of the actors were at the level of A-list superstardom they found themselves at in the following years. Tom Cruise, Emilio Estevez, Matt Dillon, Ralph Macchio, Patrick Swayze, and Rob Lowe, later branded as the “Brat Pack,” would soon find themselves the subjects of posters adorning the walls of millions of teenage girls across the globe.

A sterling performance from Diane Lane also helped set her career trajectory. Interestingly, Nicolas Cage also made a very early and uncredited appearance in the movie.

4Harry Potter and the Prisoner of Azkaban

TheHarry Potterfilm series was unfathomably successful, which obviously has a lot to do with the beloved source material, but it certainly didn’t hurt that the cast was made up of a who’s who of the finest actors the United Kingdom has to offer.

Classically trained thespians and industry legends, like Gary Oldman, Alan Rickman, Robbie Coltrane, Emma Thompson, Michael Gambon, Julie Walters, Maggie Smith, Warwick Davies, Lenny Henry and Timothy Spall (to name but a few) appearalongside the young lead castof Emma Watson, Daniel Radcliffe, Rupert Grint and Tom Felton, who byHarry Potter and the Prisoner of Azkabanhad established themselves as stars in their own right.
