Big Ass Spider. 2013.
A giant alien spider arrives in a body at a L.A. hospital and escapes, the military and a scientist team up with a exterminator to kill it.
Defiantly not one to be taken seriously even with the title, something of a nod to the old B Movies like Tarantula or Them, it does have it's funny campy moments and CGI effects that can make it more funny, this is one of those films that's up there with Eight Legged freaks, Ray Wise does make a decent Major and Lin Shaye as the sweet old scared of rats lady.
