A complaint of “inappropriate behaviour” has been made against the actor Bill Murray, leading to the production shutdown of the film he is working on, it has been reported.

According to Deadline, production on the Searchlight film Being Mortal was halted on Monday and a letter was subsequently sent to cast and crew saying: “We were made aware of a complaint, and we immediately looked into it. After reviewing the circumstances, it has been decided that production cannot continue at this time.”

The letter did not name Murray as the target of the complaint. However, Deadline named Murray and the New York Times followed, referencing an anonymous source saying that the movie was shut down because of what was described only as “inappropriate behaviour”.

Being Mortal is an adaptation of Being Mortal: Medicine and What Matters in the End, a nonfiction exploration of death and dying by surgeon Atul Gawande, and is written and directed by Aziz Ansari. Ansari also stars in the film alongside Murray and Seth Rogen.

It is not known how long the shoot will be suspended. In their letter Searchlight say: “Our hope is to resume production and are working with Aziz [Ansari] and [producer] Youree [Henley] to figure out that timing.”

Both Searchlight and a representative for Murray have been contacted for a response. Searchlight said it does not comment on ongoing investigations.
