Right now, you could be forgiven for thinking you'd woken up and found yourself in the late 1970s, but it's okay, don't panic. It's just reboot-tastic time in the world of TV, and we've got some groovy updates on the new versions of 'Dallas' and 'Charlie's Angels.'

Last week we reported that original 'Dallas' stars Larry Hagman, Patrick Duffy and Linda Gray had signed on for the update, and now we hear that producers are close to casting the pivotal role of Bobby and Pam Ewing's son, Christopher.

According to TVLine.com it's a two-horse race between Jesse Metcalfe and newcomer Alex Russell.

Producers say that the new 'Dallas' will focus on the next generation of the Ewing dynasty as they squabble over power, money and women. Josh Henderson has already signed on to play Christopher's cousin John Ross, with whom he and Jordana Brewster's character, Elena, become entangled in a love triangle.
