And nails it

Chadwick Boseman doesn't just act the part of James Brown in biopic “Get On Up,” he sings like the man, too.

“Get On Up” has taken in a disappointing $27 million haul at the box office since being released on Aug. 1, but received mostly positive reviews from critics, who were enamored with Boseman's portrayal of the R&B legend.
