Being the nerdy underdog has been a common comedic theme for Helberg, from roles in Arrested Development to Dr. Horrible's Sing-Along Blog.
For his latest project, he's writing, acting, and co-directing with wife Jocelyn Towne the film We'll Never Have Paris, which debuted at SXSW 2014. The film is based on true events of their life together.
Working on The Big Bang Theory and creating a film at the same time requires a "need" to make it all happen. The drive for the film comes from "the need to keep expressing different parts of myself," Helberg says.
