Sister chains Carl’s Jr. and Hardee’s tout a Western X-Tra Bacon Thickburger with a tie-in to this year’s "X-Men: Days of Future Past" movie. A commercial highlights the burger, which includes a charbroiled Black Angus beef patty, American cheese, onion rings, barbecue sauce and four strips of bacon, served on a freshly baked bun.

The spot also includes a social media promotion for Instagram users to post a picture of themselves eating one of the chains’ burgers for a chance to have their image morphed into one of the X-Men.
