Adam Brody (The O.C.) has been signed to play wise-cracking Wally West aka The Flash in the Justice League movie project. The Los Angeles Times reports that Brody’s deal is done but the studio won’t release the castlist until the movie’s script is given an official greenlight. Seems a little backwards but Brody sounds like a good choice for the role nonetheless.

Michelle Trachtenberg (Buffy the Vampire Slayer) Melora Hardin (Little House on the Prairie, currently The Office), and Jim Gaffigan (That 70’s Show) have all joined the cast of 17. It’s the movie about a middle-age dad (Zac Efron/Matthew Perry) who wakes up to find that he’s a teenager again. Trachtenberg’s character unwittingly develops a crush on the new boy at school who is actually her father. Hardin plays the principal at the school but it’s unknown what role Gaffigan will play. Production begins soon.

Nat Faxon (Happy Hour, Joey) has been cast in Lower Learning, opposite Eva Longoria (L.A. Dragnet, currently Desperate Housewives), Jason Biggs (Total Security), Rob Corddry (The Winner), and Will Sasso (Less than Perfect). The comedy feature tells the story of a vice-principal who tries to clean up a troubled elementary school.

Robin Bain (The Real Wedding Crashers) has completed a guest-starring role as the first live-action character on Adult Swim’s Robot Chicken series.

Amanda Peet (Studio 60 on the Sunset Strip), Billy Connolly (Head of the Class), Callum Keith Rennie (Battlestar Galactica), Adam Godley, and rapper Xzibit (Pimp My Ride) have all signed on to the X-Files movie sequel. Peet and Xzibit will allegedly play FBI agents but the studio is keeping the script so secret that they won’t say for sure.

Steven R. McQueen (Everwood) — grandson of the late Steve McQueen — has landed a lead role in a Disney Channel original movie. Minutemen centers around a trio of teen outcasts who use a time machine to become popular and help other misfits. Cory in the House’s Jason Dolley also stars.

Want to see Cary Elwes (The X-Files)? To quote The Princess Bride, “As you wish.” Elwes will play multiple parts in Robert Zemeckis’ upcoming live-action/CGI version of A Christmas Carol. Jim Carrey (In Living Color) stars.

Watch for a mini-reunion on ABC’s Boston Legal. Candice Bergen will reunite with Scott Bakula, her on-again off-again boyfriend from Murphy Brown. Bakula will, appropriately enough, play an old flame of Bergen’s Shirley Schmidt. The actor’s committed to just one appearance for now and it’s slated to air on January 22nd. It should be noted that Bakula joins a long list of Star Trek-related actors who’ve appeared on the series, not the least of whom is Legal series regular William Shatner. Stay tuned!
