John Ellis is a minor recurring character in Entourage and a character in the 2015 film, played by Alan Dale
First appearing in the season 5 episode "Gotta Look Up to Get Down," John is the fictional chairman and CEO of Time Warner, who offers Ari the Warner Brothers studio presidency after Alan Gray dies of a heart attack. Ari initially accepts the offer, but eventually turns it down and manipulates it so Dana Gordon would get the job instead of his rival Amanda Daniels. Ellis assigns Dana to work on her first 100-million dollar movie, Smoke Jumpers. However, Vince's problems with director Verner Vollstedt prompts him to stop the production in the episode "Play'n With Fire." Although he doubts Dana's management abilities, Ellis keeps her on the job. In the seventh season, Ellis briefly appears at Ari's NFL meeting. In a post-credits scene in the series finale, Ellis calls Ari in Italy and - in declaring that he wants to retire - asks the former agent to be his successor as chairman. In the movie, however, it is revealed that Ellis offered the chairmanship twice, but decided to groom Ari first by appointing him as studio head.
