LeBron James Praises 'Shooting Stars' Actors At Premiere, 'Unbelievable Job'

LeBron James is giving his stamp of approval to the actors who played him and his high school teammates in an upcoming movie ... saying the talented group of guys knocked it out of the park.

The NBA superstar and the rest of the St. Vincent-St. Mary "Fab Five" squad attended the "Shooting Stars" premiere in Los Angeles on Wednesday ... and King James was super complimentary of the final product as he addressed the crowd before the start of the flick.

James admitted it was a weird experience for him, Romeo Travis, Sian Cotton, Willie McGee and Dru Joyce III to see their lives played out on the screen ... but said the cast perfected every last detail.

"You guys did an unbelievable job," James said.

Of course, the Peacock project -- produced by Bron's SpringHill Entertainment -- is based on the book James released alongside Buzz Bissinger in 2009 ... which focuses on James and Co.'s journey to winning high school state championships.
