This month, New Line Cinema's Snakes on a Plane, which wrapped principal photography in September in Vancouver, went back before the cameras for five days of additional shooting at the Lot in Los Angeles.

In this case, it wasn't the usual reshoot, says The Hollywood Reporter, but was used to hastily assemble to fix a nagging story problem. The studio decided to create new scenes that would take the movie from PG-13 into R-rated territory. The second round of filming also came about because of intense and growing fan interest in the movie, which was directed by David R. Ellis and is not scheduled to be released until August 18.

Snakes stars Samuel L. Jackson as an FBI agent who has to fight a planeload of snakes unleashed by an assassin bent on killing a witness in protective custody. Sight unseen, the movie has grown from something of a joke into a phenomenon slithering untamed throughout the Internet.
