Casting Roundup: ‘Glee’ Extends Damian McGinty’s Stay, More Old Friends Return to ‘Grey’s’

Kate BurtonGlee‘s newest character, Irish exchange student Rory Flanagan, has build up a pretty respectable fan base in his short time on the series. So much so that Damian McGinty, the Glee Project winner who portrays Rory, has been given an extended stay on the show. We’re not certain how many more episodes McGinty will have, but the show has a history of changing things around for new characters: Heather Morris started out on the show as a behind-the-scenes dance instructor, and look at her now. Glee airs Tuesdays at 8 p.m. ET/PT on Fox. –AOLTV

In Friday’s Casting Roundup, we reported that Kate Walsh would be returning to Grey’s Anatomy in a very special episode that examined hypothetical realities for the characters. Walsh’s appearance as Dr. Addison Montgomery will play an integral part in Dr. Derek Shepherd’s (Patrick Dempsey) “alternate reality,” in which the two never split up. But an even more dramatic, more suprising character will return: Ellis, Dr. Meredith Grey’s (Ellen Pompeo) now-deceased mother, played by Kate Burton. Burton will revive her role in a reality in which she (obviously) never died, and never developed Alzheimer’s Disease. Grey’s Anatomy airs Thursdays at 9 p.m. ET/PT on ABC. –EW

House seems to love bringing back old friends, for reasons that aren’t too mysterious. And of course, there have also been a few reunions with old lovers. But this new returning guest castmember extends beyond either of these realms: House is preparing for the return of a green card wife: Karolina Wydra, who played Dominica, Dr. House’s (Hugh Laurie) own green card spouse last season. Although Dominica has been absent from the spotlight for some time now, she and the doc are clearly not entirely out of one another’s lives—as proven by her upcoming, early 2012 appearance. House airs Mondays at 9 p.m. ET/PT on Fox. –TVLine

The SyFy network has a niche audience, but it seems they’re reaching for new demographic with the new TV movie, Jersey Shore Shark Attack, which is, exactly what it sounds like. And its cast is…well, also not much different than what you’d expect. Vinny Guadagnino is the only Jersey Shore castmember to be involved in the movie, playing a reporter who covers a story of beachside rampaging sharks. Vinny is joined by more actory actors, Tony Sirico (The Sopranos). Paul Sorvino (GoodFellas), William Atherton (Die Hard), Jack Scalia (Dallas) and *N Sync’s Joey Fatone. Take all that in while you consider just how amazing this whole project sounds, and mark your calendar for its airdate sometime in the summer of 2012. –EW
