Are they planning on a follow up?

I've watched this movie several times and always enjoy it, i think the different characters go well together and there sexual orientation doesnt interfere with the movie infact i think if they were straight then it would be just another boring thriller, the characters being gay just added more enjoyment for me and i for one hope they do make a follow up or two. for all those people whining about mistakes in the film all i can say is you must have pretty boring lives to sit there noticing mistakes in movies/tv shows. please hurry and make some more movies with these two characters in them.
