1. - Val Kilmer, The Doors, 1991. During the 20-year convoluted struggle to put Jim Morrison's short, empty life on film, Charlie Sheen contacted Jerry Hopkins, co-writer of the leading source book, No One Gets Out of Here Alive, to set up a movie starring the Irish U2 rocker. Seven producers and $2m of development hell later, Oliver Stone selected Kilmer after seeing Willow, 1989. Production was then delayed by the director's (thankfully thwarted) efforts to make Evita.
2. - Dolph Lundgren, Johnny Mnemonic, 1994. A year earlier when Johnny was to be Christophe(r) Lambert, Bono was talking about supervising the soundtrack - and playing a role.
3. - Glenn Plummer, Strange Days, 1995. He passed on the futuristic singer and politico. Too close to home.
4. - Eric Stolz, Rob Roy, 1995. An early suggestion as Alan MacDonald.
