What are your favorite ensemble casts on any movie?

I'll start with mine first:

The Devil All The Time - Tom Holland (one of his only good roles ever since being Spider-Man), Robert Pattinson, Bill Skårsgard, Jason Clarke, Sebastian Stan, Riley Keough, Mia Wasikowska, Eliza Scanlen and Haley Bennett. Harry Melling.

Nocturnal Animals - Amy Adams, Jake Gyllenhaal, Michael Shannon, Aaron Taylor-Johnson, Isla Fisher, Laura Linney, Armie Hammer, Andrea Riseborough and Michael Sheen. Zawe Ashton, Jena Malone, Ellie Bamber and Karl Glusman.

Contagion - Matt Damon, Kate Winslet, Laurence Fishburne, Marion Cotillard, Jude Law, Gwyneth Paltrow, Bryan Cranston, Jennifer Ehle, Elliott Gould and Chin Han. John Hawkes and Demetri Martin.

I still have two more:

Zero Dark Thirty - Jessica Chastain, Jason Clarke, Joel Edgerton, Jennifer Ehle, Mark Strong, Kyle Chandler, Édgar Ramírez and James Gandolfini. Jeremy Strong, Chris Pratt, Stephen Dillane, Mark Duplass, Frank Grillo, Mike Colter, Harold Perrineau and Fares Fares.

Three Billboards Outside Ebbing, Missouri - Frances McDormand, Sam Rockwell, Woody Harrelson, Abbie Cornish, John Hawkes, Peter Dinklage, Lucas Hedges, Caleb Landry Jones, Željko Ivanek, Samara Weaving, Kerry Condon, Darrell Britt-Gibson and Kathryn Newton.

I probably would add The Grand Budapest Hotel and The French Dispatch but I'm just gonna stop here to make this less cluttered.
