Here is a part of what Dateline
had posted earlier today:
Director David R. Ellis has died in Johannesburg, South Africa. The Snakes On A Plane helmer passed away suddenly early this morning Los Angeles-time, Deadline has learned. Ellis was 60 years old. Cause of death is not yet known. Ellis was in South Africa preparing to direct the film KITE. The director’s live-action adaptation of the 1998 Japanese anime was set to reunite Ellis with his Snakes star Samuel L. Jackson.
He will be missed. He had some great films (Cellular, The Final Destination & Snakes on a Plane). I personally really like Cellular.
