It takes years for me to re-watch my dvd's at home or play games in the pc that I have completed before, so for sure I will not watch the leaked video anymore in the cinemas, especially when there are torrents around that you can download for free.
Depends on the movie. If a copy was leaked online I might want to watch out for it just to see if it's worth the buck to watch the movie in the theaters. But if the movie was good, like a Nolan or a Fincher flick then I guess I'd skip the leaked copy and go straight for the theaters.
