She crossed the line

Reese Witherspoon's recent run-in the with the law forced her to cancel several scheduled talk-show appearances, but you can still enjoy her more sobering work in "Walk the Line" (6 p.m. Friday, Oxygen), which netted her an Academy Award, and "Sweet Home Alabama" (6 p.m. Saturday, Oxygen), in which the actress elevates an otherwise standard issue rom-com.

Death becomes her

"The Big C" (9 p.m. Sunday, Showtime), TV's most underappreciated series, says goodbye with four one-hour episodes, starting with this one that marks the return of Alan Alda. If you haven't been watching, you're missing Laura Linney give one of the richest and most touching performances ever seen on the small screen.

Thumbs up

It's now become show-biz lore: A well-known Chicago personality goes on a date with an up-and-coming star and advises her to take control of her own talk show. Oprah Winfrey listened to Roger Ebert — and the rest is history. Expect a touching tribute to her late friend in this edition of "Oprah: Where Are They Now?" (9 p.m. Sunday, OWN).

Daily dose

None of the correspondents gets enough screen time on "The Daily Show," which is why it should be a treat to watch "Al Madrigal: Why Is the Rabbit Crying?" (10 p.m. Friday, Comedy), the comic's first one-hour special for Comedy Central.
