WATCH: Movie about Boston Marathon bombing survivor gets U.S. premiere at hospital

The U.S. premiere of a film chronicling the story of Boston Marathon bombing survivor Jeff Bauman is taking place at the hospital where he and others who were injured in the 2013 deadly attack were treated.

The movie, “Stronger,” will screen at the Spaulding Rehabilitation Hospital in Boston on Tuesday. It arrives in theaters Sept. 22.

The movie stars Jake Gyllenhaal as Bauman and “Orphan Black” actress Tatiana Maslany as Bauman’s then-girlfriend, Erin Hurley. Bauman, Hurley and their on-screen counterparts are expected to attend the premiere.

Hurley was running the marathon and Bauman was there to cheer her on when two bombs went off near the finish line. He lost his legs.
