Old man initially thanks outgoing film star (3,5)

I believe the answer is:

tom hanks

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

'old man' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'initially thanks outgoing film star' is the wordplay.
'initially' suggests taking the first letters.
'film' becomes 'M' (h9nh Fritz Lang film).
'star' becomes 'hanks' (I am not sure about this - if you are sure you should believe this answer much more).
The first letters of 'thanks outgoing' is 'to'.
'to'+'m'+'hanks'='TOM HANKS'

Can you help me to learn more?

(Other definitions for tom hanks that I've seen before include "Best Actor Oscar winner 1993, for "Philadelphia"" , "Hollywood star" .)
