I've recently seen a preview for the movie "I Don't Want to Sleep Alone," tacked onto the disc for another movie.
At one point it seems to show an Asian guy in his teens or 20s, possibly disabled, on a mattress, nude but for a disposable diaper, attended by a female.
It is a Taiwanese movie, released by Strand Releasing. I've found info about it at their site and at Amazon.
Has anyone seen this film? Is there a diapered character?
