If that’s Looper, leaves out a major player-- maybe I’m wrong?
Here’s the next one if I’m not:
Jeff Daniels, Melanie Griffith, Ray Liotta
It is (and it does miss out Jonathon Gordon-Levitt). But I don’t think there is any requirement to list three main actors in the film, are there?
How about a game where we list the gaffer, dolly grip, and caterer?
Sorry-- just thinking that it could have been some other movie-- but I guess Emily Blunt hasn’t had as extensive a career as I was thinking.
Something Wild
Emily Blunt, Meryl Streep, Colin Firth
John Travolta, P. J. Soles, William Katt
Scarlett Johansson, Rooney Mara, Chris Pratt
One of those is a major character but only their voice is heard.
Laurence Olivier, Sally Kellerman, Arthur Hill
Zoë Kravitz, Charlize Theron, Riley Keough
Adam Sandler, Jack Nicholson, Woody Harrelson.
Anger Management
Keanu Reeves, Robert Downey Jr., Woody Harrelson
A Scanner Darkly?
Wow, without Winona Ryder, I’m not sure…
but, here: Cary Grant, Irene Dunne, Asta
Yes, that’s the one I was thinking of. 
The Awful Truth
Rob Schneider, David Carradine, Henry Gibson
Big Stan
Richard Bohringer, Michael Gambon, Helen Mirren
Just clearing the board:
Carrie (1976)
The Cook, The Thief, His Wife, & Her Lover
Bob Hope, Bing Crosby, Joan Collins
