Take a Private Tour of the Newseum With 'Trumbo' Star Bryan Cranston

ABC News got an exclusive tour of the museum with Bryan Cranston and Jay Roach.

The film focuses on the true story of Dalton Trumbo, one of the highest-paid screenwriters in Hollywood during the late 1940s. Trumbo was imprisoned and added to the Hollywood Blacklist by the U.S. government for his “radical” political beliefs during America’s communist “red scare.”

After being subpoenaed to testify before the House of Un-American Activities Committee (HUAC) in 1947, Trumbo’s failure to answer a congressman’s question landed him in federal prison for a year. For the next thirteen years, he was on the “Hollywood Blacklist” and shunned by the big movie studios.

Trumbo was forced to work under pseudonyms. During his time on the Hollywood Blacklist, he penned legendary films like “Spartacus,” which is credited, in part, with ending the Hollywood Blacklist era.

After his death he was posthumously awarded an Oscar for the classic “Roman Holiday.”

The film opens nationwide Nov. 26.
