Terrence Howard allegedly assaulted composer Tex Allen in a backstage beatdown as they worked together on Broadway's "Cat on a Hot Tin Roof" last winter, according to a lawsuit.
Now Allen, a jazz pianist and the brother of Debbie Allen - who directed the play - is demanding $5 million for his alleged fat lip, according to court papers.
Allen claims the alleged assault ruined his music playing.
The suit alleges that Howard confronted Allen while he sat at the piano at around 2:30 p.m. during a Jan. 24 rehearsal at the Walter Kerr Theatre and punched him repeatedly in the face and head.
Neither Howard nor Allen would comment.
