Children Shouldn’t Play With Dead Things.  They also shouldn’t play with time machines.  Project Almanac is a story about a bunch of teens that do just that (play with time machines, not dead things) and how they have to work to correct all that they have inevitably screwed up.

The movie hasn’t even premiered yet, and Michael Bay, who produced it, is already issuing apologies for its content.

Gotta be some sort of record.
