Fox's new comedy series Grandfathered debuts on Tuesday, 29 September at 8pm ET on Fox Network where John Stamos plays a successful restaurateur who learns that he has a son and a granddaughter. The official synopsis for pilot episode reads as follows:

Successful restaurateur and man-about-town Jimmy Martino (John Stamos) is used to being the most suave, most handsome and most single person in the room. But everything changes with the surprise appearance of Jimmy's adult son, Gerald (Josh Peck), and his baby daughter, Edie. Now Jimmy has to unlearn a lifetime of blissful selfishness and grapple with the fact that he went straight from single to grandfather in six seconds flat in the all-new "Pilot" series premiere episode of Grandfathered.

Stamos said, "This is the show I've been waiting for 10 years. I mean, I couldn't be more grateful for this particular type of show. As actors we like to try to find roles that we don't normally get typecast in. And I was actively looking for a show, but something a little edgier. I wanted to play a bad guy. And my agent was like, 'Why don't you just do what you do well, and play in your wheelhouse?' I was like, 'That makes sense'."

Stamos, who is also the executive producer of the show, knows that his character does not match the traditional definition of "grandfather", but believes that it "makes it sort of interesting".

"I guess there's some irony in it... though I feel that a lot of people sort of look good at [that age]. I remember watching television when I was a kid and a 50-year-old guy was, like, Abe Vigoda. I was like, 'Well, here's a chance to change things', he added."
