Gigli sounds like a work of art to me.
I theorize that Ben had the hots for J.Lo and used his clout to have the whole 'Gigli' film put together so he could hang with her daily for 6 months or so... just long enough for them to become romantically involved.
Other than for the pussy, why else would he (or anybody else for that matter) put his big-money career at risk with an abvious bomb.
