Michael Stuhlbarg has joined the cast of the Sony sequel Men in Black III, portraying a character named Griffin. Sharlto Copley was previously in talks for the role last year, though a deal was never worked out.

Our earlier report indicated the Griffin role would be a, "fast-talking Yoda-type alien," although these details were never confirmed. The Men in Black III plot will take place in both present day and in 1969, where Will Smith's Agent J travels back in time to meet a younger Agent K (Josh Brolin). Tommy Lee Jones will reprise his role as the modern-day Agent K.

Michael Stuhlbarg is best known for his Oscar-nominated performance in the 2009 drama A Serious Man. He also appears on the critically-acclaimed HBO drama series Boardwalk Empire.
