Introducing a new level of corporate synergy, or at the very least product placement, there's an exclusive post-credits sequence for The Amazing Spider-Man 2 that can be accessed by holding up your phone and opening up your 'Shazam' app during the credits for fun phone viewing. Since my preferred phone usage is in a movie theater, I'm looking forward to it.
The catalyst song appears to be Alicia Keyes 'It's On Again', that features Kendrick Lamar. The fine folks at Coming Soon have already done all the work and you can check it out HERE if you can't wait. Or don't want to be that guy.
Looks like it's a Sinister Six film. For the uninitiated, it's a team comprised of Spider-Man greatest foes. Kind of a super villain version of the rock group Asia.
