If you’re a Tolkien nerd, then tonight’s “The Nerdist” show on BBC America will make you squee! Elijah Wood is here to give us a look at his new film “Setup, Punch,” and the blazingly funny Ben Schwartz from “Parks and Recreation” will join us too. So you better do your abdominal workouts because your stomach is about to cramp up from laughing. That’s a Nerdist promise! We’ll discover if Ben and Elijah know the difference between a “Doctor Who” creature, men’s cologne or Icelandic rock band, Matt and Jonah attempt to conquer the language barrier between America and the U.K., and comedian Katie Crown classes the joint up.
