STAYING IN? Ellen Gray's TV picks
* MUHAMMAD ALI'S GREATEST FIGHT. 8 p.m. Saturday, HBO.
The Thrilla in Manila it isn't, but this provocatively titled film about the 1971 Supreme Court deliberations over Muhammad Ali's claim to conscientious objector status during the Vietnam War packs its own quiet punch.
No attempt was made to cast an actor to play Ali, who does his own talking through extensive newsreel footage. The justices are played by the likes of Frank Langella, Christopher Plummer and Danny Glover. And the behind-the-scenes look at the Nixon-era court - where justices used to gather weekly to watch dirty movies to prepare for an obscenity case - is delicious.
* THE GOOD WIFE. 9 p.m. Sunday, CBS3.
One of Sunday's most topical dramas tackles the issue of domestic surveillance by the NSA.
* COMIC BOOK MEN. Midnight Sunday, AMC.
Kevin Smith's Red Bank, N.J., comic book store is once again at the center of the action in this unscripted show, which grew out of a podcast by the show's staff. Lou Ferrigno, the Incredible Hulk himself, guest-stars in the Season 3 premiere.
* MASTERS OF SEX. 10 p.m. Sunday, Showtime.
Things get testy between pioneering sex researchers William Masters (Michael Sheen) and Virginia Johnson (Lizzy Caplan) when their project's kicked out of the hospital and he blames her.
