Love/Hate star Robert Sheehan is set to star in comedic drama The Road Within.

The Laois-born actor will be joined by Slumdog Millionaire star Dev Patel and X-Men: First Class actress Zoe Kravitz, according to Deadline.

The movie follows a young man (Sheehan) with Tourette's syndrome, who, when his mother dies, is placed in a home by his father.

He escapes with two fellow patients - an anorexic girl (Kravitz) and his OCD roommate (Patel) - to scatter his mother's ashes in the ocean.

The Road Within begins production in July.
