I need help to get RAR password for the WAR movie that I downloaded from torrent site.

Is the torrent site external, or did you use the torrent system on this site?

If you used this site, chances are the password was posted, but you missed it, if you used an external site, you may have to read comments posted by other people, or you can use a RAR Password cracker, as they will solve your problem, though it may take a lot of time (i used it once and it took 10 minutes)
