Look for All My Children and Melrose Place alum Colin Egglesfield to likely portray the role of a young William Walker on Brothers & Sisters' upcoming flashback episode. EOnline first broke the news that Egglesfiield would be replacing one of the previously cast Rewind Walkers. Speculation is Egglesfield is going in for fellow soapster Daniel Cosgrove,who had previously been tapped to play William. I have to say, this is a good move. Egglesfield definitely brings to mind what I would envision for the cocky, philandering jerkoff who cheated on my Gidget with that tramp Holly Harper!
