On Monday's Heroes, Ellen Greene was Sylar's mom. She's a Broadway vet, and probably most recognized as Audrey from the big screen Little Shop of Horrors. John Badham, of Wargames and Saturday Night Fever fame, was the director of the episode.
Michael Shanks, Dr. Daniel Jackson on Stargate SG-1, has been the spy collaborating with the Russians and banging the VP's girlfriend on recent eps of 24.
On last Tuesday's House, Shonda Farr played the chick in for a breast exam when Wilson was hysterically freaked out on uppers House had dosed his coffee with. I recognize her most as April, the fuckbot Warren built in Buffy's "I Was Made to Love You." Coyote Ugly's Piper Perabo was the vegan House is attempting to get jiggy with.
On last week's wacky CSI (and really, hasn't this been the best season of this show?) about alien conspiracy nuts, Ally Sheedy (Breakfast Club!) was "true believer" who bit Greg and beheaded the "serpent queen." Enrico Colantoni (Papa Mars, Galaxy Quest and Just Shoot Me) was the sleazy perp. Julie Hagerty (Airplane!) was his con victim who really, really wanted to believe the serpentine aliens were here on earth, who needed to be beheaded (Paris Hilton's head is still attached, so no "mission accomplished").
On Tuesday's superb return to form for Veronica Mars (why didn't they come back from hiatus with this ep, instead of the PSA about tolerance?), Paul Rudd was the snarkalicious former rock star, Desmond Fellows. Paul, of course, you would recognize from Clueless, Friends and all the Apatow comedies. Also on VM that night was Suzanne Cryer as the Chinese teacher who had a thing for Desmond. I've had a crush on her since she was Ashley on Two Guys and a Girl, and most recently she popped up on Desperate Housewives.
On last night's Bones, Emily Deschanel's father, noted cinematographer Caleb Deschanel, was the ep's director.
