Maybe Marlon Brando seen on screen; direction by Tarantino, to begin with actor is disheartened (8)

'maybe marlon brando seen on screen direction' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'tarantino to begin with actor is disheartened' is the wordplay.
'tarantino' becomes 'films' (I can't justify this - if you can you should give a lot more credence to this answer).
'begin with' suggests taking the first letters.
'is disheartened' suggests removing the centre.
'actor' with its middle taken out is 'ar'.
The first letter of 'to' is 't'.
'films'+'t'+'ar'='FILMSTAR'

'by' acts as a link.

Can you help me to learn more?
