Abigail Breslin -- $65,000 for 4 HOURS of Acting in New Movie

Abigail Breslin's hourly rate is $16,250 -- at least when she's doing voice work for her new animated movie "Zambezia" ... this according to her contract for the film.

TMZ has obtained 15-year-old Breslin's payment agreement with film producers -- and according to the docs, she earned a grand total of $65,000 for one 4-hour recording session ... voicing the character of Zoe, an adorable bird (right).

It's not Abigail's only massive payday this year either -- back in May she signed a one-week contract for the upcoming movie "New Year's Eve" ... worth $275,000.
