Legendary film critic Roger Ebert is appearing on the big screen himself in the new documentary “Life Itself.”

Iconic filmmakers Martin Scorsese, Errol Morris and Werner Herzog pay tribute to the critic's impact on moviemaking in the clip, which also explores Ebert's relationship with Gene Siskel. The duo were seemingly always at odds, which made for some heated debate and great television as they rose to become the most important voices in film criticism.

“Life Itself,” based on Ebert's autobiography of the same name, was directed by Steve James (“Hoop Dreams”) and will be released July 4.
