Getting on the subject of audience sweetening, If the complete ABC, NBC and/or CBS sound effects libraries were acquired by Sound Ideas and made available to the public (which I am hopping that this will happen in the future), What movie would you think they might be featured on?
IMO, If the NBC crowd sounds were made available to the public, I would imagine that these crowd effects would be featured in two movies: All of the Atlanta A&T and Morris Brown performances on Drumline (including the BET Big Southern Classic Performances) and in all of the ADAA's Las Vegas Invitational games (seen on ESPN 8: The Ocho) on Dodgeball.
BTW, every sound would and probably might be carefully cleaned, free of hiss and digitally remastered for excellent sound quality
