Writer to run away with Some Like It Hot actor (8,5)

I believe the answer is:

penelope keith

'actor' is the definition.
(I know that Penelope Keith has the occupation actor)

'writer to run away with some like it hot' is the wordplay.
'writer' becomes 'pen' (something which writes).
'to run away' becomes 'elope' (I've seen this before).
'with' means one lot of letters go next to another.
'some like it hot' becomes 'keith' (some of the letters from 'like it hot').
'pen'+'elope'+'keith'='PENELOPE KEITH'

I've seen this clue in The Guardian.
