Harrison Ford - doesn't suffer fools and can be very cantankerous, but lovely once warms to you.
Ewan McGregor - gorgeous
Jamie Lee Curtis - funny as f*ck.
Bridget Fonda - lovely
Frances McDormand - doubleplus lovely
Can also vouch for Sam Neill fans upthread - charming and handsome.
on the other hand:
Bruce Forsyth - what a c*nt.
