I've just had a quick five minute think about name's I'd put in my Top 10. I came up with 33 viable names.
...May have to give me some time.
EDIT: May change the order around but, for now, this will do:
10: Nathan Fillion
9: Helena Bonham Carter
8: Alec Baldwin
7: Michael Emerson
6: Tom Hanks
5: Robert Downey Jr.
4: Timothy Spall
3: Brendan Gleeson
2: Johnny Depp
1: Sir Anthony Hopkins
Other notables who could make it on the list depending on my mood: Joan Cusack, Bill Murray, Woody Harrelson, Harold Perrineau, Michelle Rodriguez, Neil Patrick Harris, Michael Sheen, Ron Perlman, Mickey Rourke, Meryl Streep, Geoffrey Rush.
Any chance of making it a Top 20, Split?
