Let's see now, I would be sorely tempted to cast Jim Carrey as Tom Bombadil, but this is the Dillymarillion, isn’t it. I could try to pull a reverse Jackson and add Tom, but I’m not sure if our director
narfforc would countenance two directors on this thread.
Still, it’s a shame there’s no Loki in The Silm.
George Carlin is good at foul oaths: Fëanor?
Bette Midler for Yavanna.
Gilda Radnor for Varda and Gene Wilder for Manwe.
The Smothers Brothers: The Two Trees OR Fingolfin and Finarfin
Lily Tomlin for Míriel
Whoopi Goldberg: Ungoliant
Carrie Fisher: Celebrian
Rowan Atkinson: Mim the Petty Dwarf, among many others
Rodney Dangerfield as Celeborn
Rich Little: Ulmo?
Mr. T: who else but Tulkas.
And, well, no time to do more now. A cast of thousands no doubt. Must ponder where to cast Charlie Chaplin and Buster Keaton.
