Beyonce's dad tried to cash in on his famous daughter's name last year with a Destiny's Child biopic ... according to the latest batch of leaked Sony emails released by hackers.
Mathew Knowles reportedly reached out to Sony in December 2013 ... offering the studio first dibs on a movie about the girl group -- and execs seemed into the idea.
However it doesn't look like they ever came to a deal. Lifetime is reportedly planning a D.C. movie next year, but unclear if Mathew's behind that one.
Another leaked email referenced a possible Kanye West feature film. A Yeezy staffer sent an email sent to Sony Pictures honcho Amy Pascal ... pitching her a movie project involving "cinematic and technological innovation."
Great -- Kanye ranting in 4D.
