Ellen Gray's weekend TV picks
* KILLING KENNEDY. 8 p.m. Sunday, National Geographic Channel.
Ginnifer Goodwin goes up against herself Sunday as Snow White in ABC's "Once Upon a Time" and Jackie Kennedy to Rob Lowe's JFK in NatGeo's adaptation of the Bill O'Reilly and Martin Dugard best seller "Killing Kennedy." The Kennedy show is best watched for hair and wardrobe, not fresh insights into one of the biggest crimes of the 20th century.
* DANCING ON THE EDGE. 9 p.m. Saturday, Starz.
Tensions continue to rise in this miniseries about a jazz band in 1930s London. In the wake of a murder, Louis (Chiwetel Ejiofor, "12 Years a Slave") finds his account as a witness called into question while Stanley (Matthew Goode) entertains an intriguing offer from manipulative mogul Walter Masterson (John Goodman), who's taken an interest in publishing.
* AZIZ ANSARI: BURIED ALIVE. Netflix.
The "Parks and Recreation" star's new stand-up special went live on Netflix earlier this month, but since the streaming service is not tied to anything as old-fashioned as time slots, you're welcome to watch it anytime. Including this weekend.
* SATURDAY NIGHT LIVE. 8 p.m. Saturday, NBC10.
Last week, "Scandal" star Kerry Washington scored huge laughs as guest host while helping to highlight the show's embarrassing lack of African-American women cast members. If you missed it, here's your chance to see it without staying up late.
