Film star's fans found him wandering around middle of Luton (6,7)

I believe the answer is:

dustin hoffman

I'm a little stuck... Click here to teach me more about this clue!

'film star's' is the definition.
I know nothing about this answer so I can't judge whether this works.

'fans found him wandering around middle of luton' is the wordplay.
'wandering' is an anagram indicator.
'around' is an insertion indicator.
'middle of' means to look at the middle letters.
The middle letter of 'luton' is 't'.
'fans'+'found'+'him'='fansfoundhim'
'fansfoundhim' anagrammed gives 'dusinhoffman'.
'dusinhoffman' placed around 't' is 'DUSTIN HOFFMAN'.

Can you help me to learn more?

(Other definitions for dustin hoffman that I've seen before include "Star of Rain Man and Midnight Cowboy" , "Rain Man actor" .)
