TMZ Sports obtained audio of the farewell speech LeBron James gave to the "Space Jam" cast and crew on his last day of shooting ... and it's emotional stuff.
The NBA superstar -- wearing his #6 'Toon Squad' uniform -- addressed the cast and crew in Summer 2019 (before the COVID pandemic) ... and explained why it was so important for him to take the role in the first place.
"I'm gonna be honest completely with you guys -- when I found out about the project, I was like it's 'Space Jam'! It’s a movie that I grew up watching.
