Sheen joins Howard Hughes film
The Amazing Spider-Man actor has signed up for the movie, although his role has not yet been revealed, reported Deadline.
While little is known about the plot, it is thought to focus on Hughes' assistant (played by Alden Ehrenreich) and his love interest (Lily Collins).
Warren will also produce and direct the film, which has been in the works for over 25 years.
Last month it was reported that production on the film was already under way.
