While most likely known from his Scrubs work, there are few finer character actors than John C. McGinley. From Platoon to Se7en to Office Space, whether a tiny or supporting role, he always seems to make an impression. The actor will hopefully continue the trend in an upcoming biopic.

Variety reports he has joined the ensemble of Warner Bros.’ Jackie Robinson sports drama 42. Directed by Oscar-winner Brian Helgeland, the film already stars Chadwick Boseman as Robinson, Harrison Ford as Dodgers executive Branch Ricke and Nicole Beharie as Robinson’s wife, Rachel. Christopher Meloni, T.R. Knight, Brad Beyer, Toby Huss and Ryan Merriman round out the cast.

McGinley will play legendary radio broadcast Red Barber and one can him in a video below, as he talks about Robinson. At the end one can even see a snippet of an actual broadcast featuring Barber. As for McGinley, he has a busy 2012 with a role in the crime drama Alex Cross and the indies The Discoverers and Watercolor Postcards.

42 begins shooting this month and hits theaters April 12th, 2013.
