ROBOCROCK (sorry I couldn't resist!)

ROBOCROC-2013-The warden (Corey Nemec) of a zoo/animal preserve has to contend with an Australian saltwater crocodile gone wild after a space rocket crashes in it's habitat and turns it into a killer due to some nano-bots. Besides dealing with that he has to put up with a know it all, stuck up insane government scientist (Dee Wallace). Eventually, it gets loose and the usual bloody attacks on unsuspecting locals and tourists take place. A drunken fisherman is the first to go. Then a dirt biker. To make matters worse (at least for the viewer) there's a side story involving two nerds (one of them is the warden's son) being bullied at a water park. Naturally the nano-croc invades the place. A stupid army colonel (Steven Hartley) orders a lock down of the park and the nerds and two girls are trapped inside. The croc brings down a helicopter (copied from JAWS 2). The story gets even worse when a guy named Nigel (Keith Duffy) shows up to help capture the monster. The climax goes on forever with Nigel attacking the croc with a knife (bad move), the kids escape by water slide and a hunt in the sewer.

 I couldn't find any other credits for director Arthur Sinclair. It seems to be his only film but I'm sure he'll be back for ROBOCROC 2.
