"Bucky Larson: Born To Be A Star" bombed big time when it was released to theaters. It may have been because it was released in the beginning of September, when there are few people going to movie theaters. It may have been because the movie is about the porn industry, which has never been a popular movie topic for mainstream moviegoers. It may have also been because the relentless television commercials for the movie were very annoying. But I think the main reason why it bombed was that the audience smelled it for the stinker that it was. There are no laughs anywhere to be found in the movie, for one thing. But it also has a weird tone, like it was written by a dirty-minded and mean-spirited eight year old. It's not very audience-friendly, to put it mildly. The cast is spirited, but they can do absolutely nothing with the terrible script.
Oh, one more piece of evidence for its badness: The end credits for this 2011 release list a 2010 copyright, suggesting that Columbia Pictures didn't know what to do with the movie for quite some time.
