Samuel L. Jackson on Sunday to discuss the recent passing of Bernie Mac and Isaac Hayes, both of whom co-starred with Jackson in the upcoming film “Soul Men.”

The movie stars Mac and Jackson as estranged members of a legendary soul group who reluctantly reunite to attend the funeral of another member of the group. Hayes plays himself in the film.

Jackson said he and Mac had to sing the Hayes song “Do Your Thing,” from the 1971 soundtrack to “Shaft,” as part of the film, which was a bit intimidating when the man who sang it originally was standing a few feet away.

“A little pressure in that,” laughs Jackson. “When you’re standing there singing and dancing, and you’re singing the guy’s song and he’s watching you do it, it’s a little pressure.”

“But he gave us all these props because we do what we do,” Jackson added.

The Kangol-wearing film star said he was still in bed when news of Mac’s death broke in the morning hours of Aug. 9.

“Somebody woke me up and told me. I got up to make sure, because there had already been a false alarm earlier that week, so I wanted to make sure it was true, first of all, before I reacted in any way,” Jackson said. “And then to find out that he was dead, it was sad because I had just seen the film earlier that week. I immediately wondered had he seen it, would he have realized we had done something really great together. I found out from his manager that he hadn’t [seen it]. That’s a shame, but hopefully, the legacy of it all, everybody who sees the film they’ll know we did something worthwhile.”

“Life is short, so, we have to enjoy it and do as much as we can,” he continued. “I’m really glad that I had the opportunity to work with Bernie, because he was a friend and colleague, somebody that I loved a lot, and it was a joy to finally be able to do a film with him. It’s a great film, great performance by him. I hope that when the film comes out, people will go and see it and enjoy it and remember him as the wonderful, jovial, full-of-life person that he was.”
