“Jackass 3D” owned the weekend box office, earning $50 million in North America — more than double the take of “RED”, which pulled $22.5 million, and the strongest opening since “Inception” debuted with $60.5 million back in mid-July.

I’m not surprised that Johnny Knoxville and his pals topped the charts again — the previous “Jackass” movies both opened at number one, and the added appeal of 3D was bound to spike the gross … pun entirely intended.

But still, right? Fifty million dollars! That sure buys a lot of splints and unguent. And yes, I’m still planning to see it when I can find the time.
