'Parker Lewis' Star -- SUES Filmmakers Over Leg Shattered In Boat Crash 'Parker Lewis' Star SUES Filmmakers Over Leg-Shattering Boat Crash EXCLUSIVE 6/13/2013 12:50 AM PT

Corin Nemec -- star of the '90s sitcom "Parker Lewis Can't Lose" -- is suing the filmmakers he claims are responsible for the boating accident that mangled his leg, insisting it's THEIR fault he suffered permanent injuries ... and now he's out for payback.

As we previously reported, the accident occurred in January in Belize -- Nemec was riding on board a boat to the set of B-horror movie "Rise of the Dinosaurs" ... when the vessel slammed violently into a submerged barge.

Nemec told us the crash sent him flying into the side of the boat -- and as a result, he broke his femur in 3 places, lost TONS of blood, and needed emergency surgery (including blood transfusions) to keep him alive.

Now Nemec has filed a lawsuit, claiming the filmmakers were negligent in hiring an operator who drove the boat recklessly. And to make matters worse, Nemec claims the filmmakers weren't even carrying required worker's comp insurance.

The suit says the accident left Nemec with permanent injuries ... and that six months later, he's still being treated. He's suing for unspecified damages, exceeding $25,000.

We reached out to the production company behind the film ... no word back so far.
