Gil Birmingham plays Jacob's papa. Billy Black. Gil said on his official Facebook page how he feels about being finished with the Twilight Saga movies.
It's been 5 years of filming since 2007 to 2011. That is a long acting job for most actors to be on one movie series.
This won't be the end of Gil Birmingham for the Twilight fans though. Gil still plans on visiting Twilight Conventions and will be appearing this weekend in Arlington, VA.
