Conner Flynn at Technabob suggests that this movie be entitled Batman and Captain Picard Fight Aliens: Prometheus: First Contact Rises. That is an outstanding idea!
I propose that Patrick Stewart play the role of Batman and Ben Affleck play Picard. The xenomorphs would require multiple actors, but Robin Williams should play the Queen.
To flesh out the supporting characters, bring in Gilbert Gottfried to play Alfred Pennyworth and the current Lassie to play Commander Riker.
Artist Jimsmash has the story concept ready to go. Hollywood, get to work.
