NBC expands ‘SNL 40th Anniversary Special’ to more than three hours

NBC is already making a big deal of the 40th anniversary of “Saturday Night Live” — and now it’s making it a little bigger.

The network revealed late Thursday that it’s expanding Sunday’s “SNL 40th Anniversary Special” by 30 minutes, which means it will start at 8 p.m. and end at 11:30.

The special — airing live on the East Coast but on tape on the West Coast — will be like a super-sized version of a regular “SNL,” with live skits, taped segments and musical performances.

Guests include Justin Timberlake, Robert De Niro, Steve Martin, Jim Carrey, Miley Cyrus and many more. Old cast members like Kristen Wiig, Chevy Chase and Martin Short will also turn up.

Two questions right away: Where in the broadcast will executive producer and creator Lorne Michaels suddenly appear with one of his famously laconic cameos? And what will they do for the “cold open” — maybe revive the famous Chevy Chase pratfall?

And if all that’s not enough “SNL” for your weekend, on Saturday night, in the comedy revue’s usual 11:30 p.m. slot, NBC will repeat the first “Saturday Night Live,” first broadcast on Oct. 11, 1975, and hosted by George Carlin.
