The character of Lena was named after Lena Luthor, the daughter of Superman's nemesis, Lex Luthor.
There were over 35 drafts of the script. During the writing process, the script went from the original version, which was a very light hearted comedy, to an incredibly dark version of the film. This version included moments such as the lead female getting brutally bashed and almost raped in a parking garage. Producer Lisa Shaunessy and writer Shannon Browning reworked the story to bring it back to the more light hearted tone of the original script.
