Heroes Vs. Life On Mars: Which New Family Member Is Less Annoying?This week, everybody is getting a blast from the past. Chuck is running into his ex-girlfriend, Sam is meeting his mother, Back To The Future-style on Life On Mars, and the Petrellis just can't seem to shake their daddy issues on Heroes. We've got behind the scenes clips and promos for all.Monday: Adorably dorky Chuck features yet more overly attractive women getting thrown at the nerd with the spy computer in his brain this week. In "Chuck Versus Tom Sawyer" the lucky lady that gets to play with Chuck's pocket protector is none other than his ex-girlfriend. Chuck is on at 8 PM on NBC. Chuck Promo: The Petrelli clan is all riled up and ready to fight on Heroes this week, and it finally looks like some sense has been smacked into Peter, thanks to his overly dramatic over-the-top Poppy. "Eris Quod Sum" is on NBC at 9 PM. Heroes Promo: Heroes Mohinder Behind The Scenes Footage: No Sarah Connor Chronicles this week.

Promo For Eleventh Hour: This week in Life On Mars' incredibly long-titled episode, "Have You Seen Your Mother, Baby, Standing in the Shadows?", we get to meet some members of Sam's family from the past, which is now the present, because he's traveled back in time but not really. (Well, you get the idea.) The American revamp of this British hit is on 10 PM on ABC. Life On Mars Promo: Jimmy is causing more trouble by snapping pics of Clark saving Lois, again. Will Clark's "Identity" be revealed this week? I'm guessing no. But if it's got more of hottie Sam Witwer as Doomsday, I'm game. Smallville is on 8 PM on the CW.
