 Larry Cohen (I) (qv) worked on the script while he tried to get  his screenplay _Phone Booth (2002)_ (qv) sold. In a New Yorker  article he says he wrote the film with the intention that it would  be the direct opposite to Phone Booth (Phone Booth is about a man  trapped on a phone in a booth, while this movie is about a man who  is still trapped on a phone but can go anywhere). However, his  friends told him that he had written the same screenplay twice.
