Notice the capital "S" on Subway. Godzilla is going up against the sandwich chain, not a series of underground cars.
Toho, the company that owns the rights to Godzilla and the Godzilla movies, is suing Subway for using the monster in its ads. Now, the ads never state that the monster is Godzilla, but he looks a lot like the famous monster and he does invade Japan in the spots. Subway never got Toho's permission, and aired the spots during American Idol and other TV shows, pushing their "Five Dollar Foot Long" campaign.
