King Jack is a 2015 American coming-of-age adventure drama film written and directed by Felix Thompson in his directorial debut.

The film stars Charlie Plummer, Cory Nichols, Christian Madsen, Daniel Flaherty, Erin Davie and Chloe Levine, and follows a 15-year-old boy who befriends his introverted cousin while facing off against a sadistic school bully.

The website's critical consensus reads, "Hard-hitting and honest yet sensitive, King Jack is an uncommonly affecting coming-of-age drama and a powerful calling card for debuting writer-director Felix Thompson.

[6] In the Los Angeles Times, Michael Rechtsaffen said that "thanks to a strongly rooted lead performance by Charlie Plummer as a 15-year-old small-town kid who's well on his way to a stint in juvenile detention, "King Jack" still strikes a resonant chord.

"[7] On IndieWire, David Ehrlich said that "writer-director Felix Thompson's first film is a sensitive and self-possessed debut that clocks in at 76 minutes and doesn't waste a single one of them"[8]
