Q. Will Sell This House return?

Sort of. After a long run as Sell This House, the A&E series was retooled as Sell This House: Extreme last year. A new, 11-episode Extreme season begins July 7. A&E says the new episodes will be “bigger than ever” as the team tackles “massive renovations” to get homes sold. Tanya Memme returns as host, with construction expert Charlie Frattini and a new designer, Daniel Kucan.

Q. I have viewed a movie starring Kevin Costner as an instructor for U.S. Coast Guard “rescue swimmers” on TNT and USA several times. Unfortunately I have always missed the opening credits. What is the title and year produced? Who played his star pupil Jake Fisher and his girlfriend?

That’s The Guardian, from 2006. Ashton Kutcher played Fisher, and Melissa Sagemiller was Fisher’s girlfriend, Emily Thomas.

Q. What happened to the TV show Brothers and Sisters with Sally Field on ABC? I don’t remember ever seeing a finale.

The series, which also starred Calista Flockhart and Rachel Griffiths, had its last new telecast in May 2011 after a five-season run. The last episode was not officially a series finale — the cancellation came a bit later — and some plot threads were left unfinished. Still, it ended on a note that could serve as a conclusion, with the characters dancing happily at a wedding and a summing-up comment by Field’s character. The entire series is available on DVD and at Netflix and Amazon.com on streaming video.

Q. Legend was Richard Dean Anderson’s first post- MacGyver project. It was a western with a humorous flair. Has it been released on DVD?

Legend, which marked Anderson’s return to series TV after some post- MacGyver movies and specials, aired in 1995 on the old UPN network. He played Ernest Pratt, a writer who assumed the identity of Nicodemus Legend, a character in Pratt’s dime novels. Pratt/Legend worked with Janos Bartok, a professor and inventor played by John de Lancie (Q on Star Trek: The Next Generation and sequels). I do not know of any authorized release of the series on DVD or other current formats.

Q. Is Ducky dead on NCIS?

The show’s season-ending cliffhanger included an explosion that could have hit several characters. Donald “Ducky” Mallard (played by David McCallum) was not at the explosion scene, but had a heart attack just after getting a call and saying, “It’s imperative that no one touch any of the deceased.”

In an online post, NCIS executive producer Gary Glasberg said that “you’ll get all the answers you’re looking for” when the series returns for its 10th season in the fall.
