We caught up with Quay Huncho outside of LAX — fresh off his time on the set of his bank-robbing heist "Cash Out" and he had plenty of love for his costars — especially John Travolta, who gave the star rapper some potential Oscar-winning advice.

Quay says John simply told him to be relaxed on set — and be himself at times, which is a little strange considering they're actually portraying someone else.

That being said, most successful actors still don't have filmographies as acclaimed as Travolta's so, yeah.

Although there's no set release date or trailer, Quay was especially pumped, shouting out director Randall Emmett and his costars ... including Noel Gugliemi, who he flicked it up with several times on the "Cash Out" set.
