Title: Stag (film)
Content:  Brendan Kelly of Variety called it "an efficient psychological thriller" that "becomes a tad predictable". Nathan Rabin of The A.V. Club called it "stagey, badly written, and mind-numbingly predictable". TV Guide rated it 2/4 stars and called it "a sometimes gripping, sometimes frustrating suspense drama". Kevin Thomas of the Los Angeles Times called it "relentlessly obvious and tedious". It has been compared to 1998's Very Bad Things, a film which also revolves around the death of a stripper at a bachelor party. The producers of Very Bad Things were not aware of Stag while the movie was being written. By the time Very Bad Things began being financed, the producers had found out about Stag, and changes were made to the script to make it less similar.

Title: Very Bad Things
Content:  Very Bad Things was noted for having a very similar plot setup to Stag, a film which originally aired on HBO in June 1997. Director Peter Berg told The A.V. Club in 1998, "See, the first time I'd ever heard about Stag was after I had finished writing the screenplay for Very Bad Things. When we were at the point of getting the film financed, we had a lawyer look over the script and the film to make sure there weren't too many similarities. I mean, there were things we had to change; for example, one of the characters in the movie was a baker, and there was also a baker in our script, so we had to change some very minor things. But as far as I understand it, the two films take very different approaches to the material. I will say this: I think it would be interesting to get, like, three different directors—say, Soderbergh, Spielberg, and Coppola—and have them all tell the exact same story in a different way."
