NEW YORK (AP) -- Betty White demonstrated how it's done as host of this week's ''Saturday Night Live.''

The “Saturday Night Live” player is starring in “MacGruber,” a film parody of the “MacGyver” TV series.

AUSTIN, Texas (Hollywood Reporter) - "Saturday Night" seems like such a natural idea for a documentary -- charting the week of writing and preparation that go into an episode of "Saturday Night Live" -- that it's hard to believe it hasn't been made before. James Franco got the idea after hosting the show in September 2008, and exec producer Lorne Michaels gave him the go-ahead to bring in cameras and record an entire week.

LOS ANGELES (Reuters) - After weeks of speculation, octogenarian actress and "Golden Girl" Betty White is taking her motherly brand of humor to sketch comedy show "Saturday Night Live," the show's producers said on Thursday.
