Longtime Disney production executive Louie Provost is leaving the companys fold.

Insiders say the executives contract was up, with Provost set to depart at the end of this year.

Provost joined the company in 2007 as an assistant tothen-president of production Oren Aviv.He climbed up the production and development ranks, making it to The Hollywood Reporters Next Gen list in 2015 and to his current title, executive vp, production as he oversaw a range of live-action titles. Among those were the $ 1 billion hit Aladdin, the fondly-regarded The Muppets, the big-budget Maleficent and Maleficent: Mistress of Evil, and the personal Petes Dragon. Saving Mr. Banks and Rescue Rangers were also movies he shepherded. My time at Disney has been unforgettable, Provost said in a statement. During my seventeen years here, Ive had the opportunity to work with incredible filmmakers making projects we loved on all sorts of different scales, everything from big blockbusters like Aladdin and Maleficent to inventive comedies like Rescue Rangers and bold reinventions like Petes Dragon. Im so fortunate to have had mentors like Alan Bergman, Alan Horn, Sean Bailey, and David Greenbaum through the years, and am grateful for their trust and support during my time here.

The executive is still actively working on the live-action Lilo Stitch movie and the upcoming Alexander and The Terrible, Horrible, No Good, Very Bad Road Trip.

Provosts departure comes as a confluence of industry and studio factors conjoined. Provost rose up the ranks working under Sean Bailey, the live-action head who left earlier this year. In his place, David Greenbaum, who ran Searchlight Pictures with Matthew Greenfield, took over the lead of the division, which has had a checkered record of success. Greenbaum will be trying to find his own path into live-action.

A second factor is Hollywoods current stagnation of upward mobility, which has left many production execs with few paths for growth and professionally unfulfilled.
