Beatty’s as-yet-untitled film will debut sometime in the autumn via 20th Century Fox and New Regency.

The key cast includes Lily Collins and Alec Baldwin.

Beatty dropped into Las Vegas to present Milchan with the Legend Of Cinema Award on Wednesday.

Milchan also took part in a panel discussion about the making of The Revenant, which has grossed more than $500m worldwide and earned three Oscars.
