Warren Beatty Flies High With Alden Ehrenreich in Final 'Rules Don't Apply' Trailer

"You make an old guy courageous."

The final trailer for Warren Beatty's Rules Don't Apply has been released, and it's full of mustached body doubles, actresses under contract and banana-nut ice cream.

Beatty wrote, directed, produced and stars in the New Regency title, playing Howard Hughes, the wildly unpredictable billionaire, who subjects his employees — an aspiring young actress (Lily Collins) and her ambitious young driver (Alden Ehrenreich) — to his eccentricities.

Alec Baldwin, Ed Harris, Matthew Broderick, Annette Bening, Megan Hilty, Martin Sheen, Steve Coogan, Candice Bergen and Oliver Platt round out the dramedy's star-studded cast.

The film has been a longtime passion project for Beatty, as the actor-director hasn't helmed a film since 1998's Bulworth.

Fox will release Rules Don't Apply in theaters Nov. 23.
