'Ringer' Star Zoey Deutch -- The $25,000 Bust BEFORE She Hit It Big

Disney star Zoey Deutch -- the daughter of "Back to the Future" actress Lea Thompson -- raked in $25,000 for her first ever network acting gig ... but the gravy train came to a screeching halt because the show got canned before it ever aired.

TMZ has obtained a copy of Zoey's contract for an ABC pilot entitled "Hallelujah" -- filed recently in L.A. County Superior Court -- and if you haven't heard about the show, don't worry ... it never got picked up.

According to the contract, Zoey (who starred on Disney's "The Suite Life on Deck") was paid $25,000 for 17 days of shooting -- presumably for the pilot -- with a promise of another $25,000 per episode thereafter if ABC picked it up.

Problem is ... ABC passed on the pilot this fall -- and the show's future is unclear.
