John Stamos

BEVERLY HILLS, Calif. — Two shows at the same time playing a member of two families: that’s what John Stamos is up to these days.

He stars in the upcoming Fox sitcom “Grandfathered,” playing a freewheeling bachelor who discovers he has a son and infant granddaughter he never knew about.

Meanwhile, he’s shooting “Fuller House,” the much-awaited reboot of his enduring 1990s comedy that centered on three single men raising kids. It’s being revived by Netflix.

Speaking recently to TV critics, Stamos said his dual roles are two sides of the same coin: unconventional family life.

He cited “Full House” as an early example of a comedy built around an unconventional homestead.

And now, on “Grandfathered,” he plays a man who, at age 50, must come to terms with two generations of a family he never imagined.

“It’s ‘family first’ on this show,” declared Stamos.

His co-stars include Josh Peck as his grown son, along with Paget Brewster, who plays the mother of Stamos’ son, conceived during a one-night-stand.

Meanwhile, Stamos is producing and starring in a 13-episode cycle of “Fuller House,” a spinoff where Candace Cameron-Bure stars as a pregnant and recently widowed mother of two.

Jodie Sweetin, who played her sister in the original, and Andrea Barber, who played her friend, move in to help her.

Bob Saget, who played the widowed father of the three girls in the original series, and Mary-Kate and Ashley Olsen, are also being courted to be in the new series.

Netflix has said “Fuller House” will debut next year on the streaming television service.

“Grandfathered” premieres on Fox Sept. 29.
