1) “Asia” debut, 8 p.m., BBC America. Here is nature filmmaking at its best. This first hour (of seven) sticks to the water, from awesome manta ray (with 15-foot wingspan) to a two-inch mudskipper (shown here), a fish out of water (literally) that skims the surface. We see aome fish frantically trying to outrun sharks; others join with snakes for a two-tiered hunting party.
2) “Saturday Night Live,” 11:29 p.m., NBC. It’s Timothee Chalamet’s second turn as hosted. When he did it last season, the Boygenius trio was music guest; this time, he does that himself … and will probably do it well. In movies, he’s sung zestfully as Willy Wonka and twangily as Bob Dylan.
3) Figure skating. The women went first in this year’s U.S. championships, but now the others have their turn. From 2:30-4:30 p.m. today, NBC has the men’s short program and the free-dance finale; from 8-10 p.m., the USA Network has the pairs finale. Overlapping that is coverage on Peacock, from 11 a.m. to 4:30 p.m. and from 7:35 to 10.
4) “NCIS” and “NCIS: Origins,” 8 and 9 p.m., CBS. On Monday, both shows return to new episodes; CBS will be rerun-free (except for Saturdays). For now, here are two more reruns: a scramble to keep a tell-all book from ruining a Marine’s Christmas; and Franks’ rush to get a condemned prisoner to tell where he buried a body.
5) “From Roger Moore With Love” (2024), 8-10 p.m., CW. The son of a London cop, Moore became an actor almost by accident. He starred on TV (“The Saint,” “Maverick”), then was James Bond seven times, tying Sean Connery and topping Daniel Craig (5) and Pierce Brosnan (4).
