Hollywood Harlow in full effect -- Jack Harlow is on set for his acting debut in the "White Men Can't Jump" reboot ... and TMZ Sports has the vid!!
As we previously reported, the "First Class" rapper landed the gig after crushing his first-ever audition ... playing Billy Hoyle, which was Woody Harrelson's role in the original film back in 1992.
The project appears to be well on its way ... as Harlow was spotted making his rounds on set at a basketball court in Venice.
Of course, Harlow is working alongside Sinqua Walls in the flick .
