Tonight’s Chuck had some great movie references. Topping the list is probably Sgt. Al Powell, played by Reginald VelJohnson. He also eats Twinkies in both shows. Astute readers will remember VelJohnson playing Sgt. Al Powell in Die Hard! Michael Rooker plays the hostage negotiator. The bad guy is known as "Ned" Rhyerson (a character from Groundhog Day).
There’s probably more, but those were great.
