Advertising has gone so meta that only teleportation can explain it. In this ad, Jumper star Hayden Christensen uses his teleporting gift to throw himself into Serena Williams' computer ad. So basically he's leaping out of a commercial for the film, which is about teleporting mutants, and into an old ad for Hewlett Packard, starring Williams. It's a new mutant kind of advertising synergy, more like cross-cannibalism than cross-promotion. Be very scared. 'Jumper' ad leaps between products [Variety]
