8 Upcoming Movies That Had Massive Reshoots

4. The Shallows

The Reshoots: Barely two months before the shark movie's release date, lead actress Blake Lively was seen returning to the set to reshoot several sequences.

This doesn't sound particularly out of the ordinary, right? Well, Lively was in fact pregnant during the reshoot, which implies how absolutely vital it probably was: the studio were prepared to have Lively get back in the water with baby in tow.

Will It Be Any Good?: The reshoots apparently went off without a hitch, but it's still faintly alarming that the studio had to call back a pregnant Lively to fix things that late in the game. It does sound like a movie that perhaps isn't working as well in post-production as they hoped.

Then again, the trailer looks tense interestingly minimalist, so it could still end up being one of the year's big sleeper hits.
