I visited Libya in September 1996 for the 27th anniversary of the 'revolution' - a military coup that a 27-year-old Gadhafi led to topple the monarchy and since which he has ruled.

It definitely wasn't like, 'Hey, I'm going to steal that, and nobody's going to know.' The original 'T.R.O.Y.' came out in 1992, and it was like a 20th anniversary kind of thing. All of those intentions were there for it to be resurrecting a classic for a new generation. I tried to honor it.
