If you want to get really anal, David Tennant and Richard Grant were both in an episode of the very funny miniseieres Posh Nosh.
Not a movie, but in the Season 6 live episode of 30 Rock, in the 60’s flashback, Kenneth can be seen handing out papers…because he’s immortal of course.
Also Jane played Dusty Springfield with a sort of Southern accent, when in fact she’s English.
