They Came Together has pretty much everyone you'd want for a comedy cast: Amy Poehler, Paul Rudd, Ed Helms, Michael Ian Black, Jason Mantzoukas, Cobie Smulders, Christopher Meloni, and more.  Plus, the romantic comedy parody was scripted by Wet Hot American Summer co-writers David Wain and Michael Showalter (with Wain directing), so I think we're in for a treat.  They Came Together follows the budding relationship between Joel (Rudd) and Molly (Poehler) that starts off rocky when "his big corporation is the one that threatens to shut down her quirky knick-knack store."  The movie will satirize all the rom-com tropes, so of course Poehler will be stuck in a wedding dress at one point, as seen the first batch of set photos.  And of course Michael Shannon will wield a sword!
