Yup, just when you think that the film can't get any more stacked, it will feature Red Hot Chili Peppers bassist Flea (or Michael Balzary) as Brandon, who is Chloe's older gay brother in the original memoir. Besides his work in music, Flea also has a pretty robust body of work in film and television, best known for voicing Donnie Thornberry in the beloved Nickelodeon series The Wild Thornberrys. Recently, he has also appeared in Baby Driver.
