TV highlights: May 22-28, 2011

TV THIS WEEK

SUNDAY

What if a classic science-fiction scenario became fact? That possibility is imagined in the special “When Aliens Attack.” And it’s all sci-fi farce when “Family Guy” completes its spoofing of the original “Star Wars” trilogy with a send-up of “Return of the Jedi.” (National Geographic, 5 and 8 p.m.; Fox,

9 p.m.)

Tom Selleck and his manly mustache star in the made-for-TV thriller “Jesse Stone: Innocents Lost,” while Donald Trump and his crazy comb-over pick a winner on the season finale of “The Celebrity Apprentice.” (CBS, 9 p.m.; NBC, 9 p.m.)

MONDAY

Follow the money — tons of taxpayers’ money — when events surrounding the multibillion-dollar Wall Street bailout are revisited in the docudrama “Too Big to Fail.” With Paul Giamatti, above, as Federal Reserve Chairman Ben Bernanke. (HBO, 9 p.m.)

TUESDAY

It’s a fat-to-fit fight to the finish, and famous feet are feted, on the respective season finales of “The Biggest Loser” and “Dancing With the Stars.” And golly gee, it’s the sophomore-season finale of “Glee.” (NBC, 8 p.m.; ABC, 9 p.m.; Fox, 9 p.m.)

WEDNESDAY

Whichever singer claims the title on the season finale of “American Idol” — sadly, it won’t be Pia Toscano — the real winners might just be Jennifer Lopez and Steven Tyler, who acquitted themselves nicely in their first term at the judges’ table. (Fox, 8 p.m.)

THURSDAY

Control-alt-delete is not an option: The potential consequences of hacker attacks and computer viruses upon our nation’s banks, utilities and other infrastructure are considered in the special “Code Wars: America’s Cyber Threat.” (6, 7, 9 and 10 p.m. CNBC)

FRIDAY

Look up the word “brooding” in the dictionary, and you’ll see a picture of Robert Pattinson. The “Twilight” star deploys his signature expression in the decidedly non-vampiric 2010 melodrama “Remember Me.” With Pierce Brosnan. (Showtime, 9 p.m.)

SATURDAY

Turning an “SNL” sketch into a feature film is often a sketchy proposition; for every “Wayne’s World” or “Blues Brothers,” there’s a “Coneheads” or “Blues Brothers 2000.” And then there’s 2010’s “MacGruber,” with Will Forte, below. (Cinemax, 10 p.m.)
