Among the film industry luminaries on hand to offer a thumbs-up to Ebert's career are Werner Herzog, Martin Scorsese and Errol Morris. Ebert's widow, Chaz Ebert, is also interviewed in the film.  

"He made it possible for a bigger audience, a wider audience, to appreciate cinema as an art form because he really loved films," Scorsese says about Ebert.

The film was directed by Steve James, who helmed the 1994 documentary Hoop Dreams, which Ebert and Siskel had championed. Life Itself is based on Ebert's 2012 autobiography of the same name. Scorsese and Steven Zaillian executive produced the doc.

Life Itself premiered at the 2014 Sundance Film Festival and is being released July 4 in theaters and on VOD by Magnolia Pictures. Producers raised $150,000 on crowdfunding site Indiegogo to supplement the reported $1 million budget.
