Having wrapped up his stint in Middle-earth, “Hobbit” star Martin Freeman has joined the cast of “Captain America: Civil War.”

The film is heavily anticipated among fanboys because it is expected to feature a smackdown between Captain America and Iron Man. Marvel released the news on its website, as is its habit, but did not give any specifics about what role Freeman would assume.

The comicbook sequel hits theaters on May 6, 2016, and is directed by Joe and Anthony Russo, who oversaw “Captain America: The Winter Soldier.” The cast is expected to include Robert Downey Jr. as Iron Man, Chris Evans as Captain America, Jeremy Renner as Hawkeye and Anthony Mackie as Falcon, among other costumed heroes.

In addition to playing Bilbo Baggins in the “Hobbit” trilogy, Freeman has appeared in “Sherlock,” the “Fargo” TV series and the original U.K. version of “The Office.” Most recently, he has filmed Tina Fey’s untitled wartime black comedy.
