"Oh, well, at least it's not duct tape -- that stuff tastes terrible."
The trailer for the upcoming (2009) flick The Unborn reveals it will bring forth a new first for bondage scenes in mainstream movies: the first ring gag in a mainstream production.
My "Firsts" chart lists "Tokyo Decadence" as the first ring gag in a mainstream film, but it's a problematical ring gag -- one of those rings set in a large leather gag, with what appears to be one of those devices you put in sinks to strain out large foodstuffs inside it.
Thhere's also the matter of "mainstream." Tokyo Decadence primarily played the art house circuit in the US but never really made the megaplexes. It's got enough strong sexual bondage imagery that it's regarded as softcore porn by some. However, it did show up in Blockbuster and most of the other big video rental outfits. So it's kinda mainstream and it's kinda not.
The Unborn is produced by Michael Bay ("Transformers") and written and directed by David S. Goyer ("Ghost Rider" and "Blade: The Series") it's pure-D mainstream stuff. If it shows up in theaters come 2009, and it almost certainly will, consider who's behind it, I'll put it on the Firsts Chart.
Makes the Oscars pale by comparison, eh?
