Jim here. Paramount just listed Jackass 3-D as a 2010 production (via Cinematical) and so it seems Johnny Knoxville will ride again - and this time will be making you squirm in three dimensions! :-)Sounds like a natural fit to me. Why not? Jackass tends to push visual buttons so S3D should up the ante a bit. Or a LOT. :-)
No release date has been slated yet.
