Pat C. discovered “Arrested Development” last week. “Watched the first nine episodes,” she e-mailed. “Funny!”

Gone from network TV since February 2006, when Fox burned off the last four episodes against the opening ceremonies of the Winter Olympics, “Arrested Development” is still finding new fans, proving just how groundbreaking it was then and how absurdly funny it remains today.

The comedy about the deeply and hilariously dysfunctional Bluth family also continues to make news, the latest tidbit being that creator Mitchell Hurwitz is halfway through a script for an “Arrested Development” movie, for which the entire cast has agreed to return.

DVD (or on-demand video) is actually the perfect format with which to discover “Arrested Development.” And with the movie looking as if it will actually happen, this is a great time to do that. Here’s a primer.

Michael Bluth

The responsible second son of the family, a widowed single father, reluctantly stepped in to hold the clan together after patriarch George Sr. went to prison for securities fraud.

Played by Jason Bateman, who’s been busy in movies: “The Switch,” “Couples Retreat,” “Up in the Air” and “Juno.”

Lindsay Bluth Funke

Michael’s twin sister (who turned out to have been adopted) dabbled in do-good causes but had little true feeling for anyone but herself.

Played by Portia de Rossi, who starred in the unfortunately short-lived comedy “Better Off Ted” and recurred on “Nip/Tuck.” Before “AD,” she played Nell on “Ally McBeal” (1998-2002).

George Oscar Bluth

Known as GOB (pronounced like the Bible’s Job), he’s the Segway-riding magician and ladies man who failed as president of Bluth Corp.

Played by Will Arnett, who stars with Keri Russell in Hurwitz’s new comedy, “Running Wilde,” this fall on Fox. Arnett also played Alec Baldwin’s rival, Devon Banks, on “30 Rock” and has voiced animated characters in movies including “Despicable Me.”

George Michael Bluth

Michael’s reserved teenage son was, like his dad, an island of sanity among the crazy Bluths.

Played by Michael Cera, the breakout star of the cast. Cera, 22, plays the title character in “Scott Pilgrim vs. the World” and starred in “Nick and Norah’s Infinite Playlist” and “Juno.”

Buster Bluth

A mama’s boy, he rebounded after his hand was bitten off by seal.

Played by Tony Hale, who had the recurring role of Emmett Milbarge on “Chuck” and co-starred with Andy Richter on “Andy Barker, P.I.” Before “AD,” Hale had guested on TV series as diverse as “Dawson’s Creek,” “Sex and the City” and “The Sopranos.”

Tobias Funke

A psychiatrist, married to Lindsay, he yearned to join Blue Man Group and got ready by repeatedly covering himself with blue paint.

Played by David Cross, who will join the cast of “Running Wilde” this fall. Cross also co-wrote and starred in the British comedy “The Increasingly Poor Decisions of Todd Margaret.” Before “AD,” he teamed with Bob Odenkirk on cult favorite “Mr. Show With Bob and David” (1995-98).

George Bluth Sr.

The Bluths’ “Pop-Pop” escaped from prison, hid in the attic and was disclosed to have business dealings with Saddam Hussein. Also invented the lethal snack-food maker the Cornballer.

Played by Jeffrey Tambor, who starred with John Lithgow in the single-season sitcom “Twenty Good Years” and played Sid in “The Hangover.” Before “AD,” in a long career in movies and TV, he played Hank Kingsley on “The Larry Sanders Show” and Murray on “Max Headroom.”

Lucille Bluth

The Bluths’ self-absorbed mother was so unsatisfied with her own offspring, she adopted a Korean boy and mistakenly called him Annyong, Korean for “hello.”

Played by Jessica Walter, who went on to play Tabitha Wilson on “90210” and co-star on “Gravity” and “Saving Grace.” Before “AD,” she was well-known for TV and movie roles dating to the 1960s.
