Sylvester Stallone will be starring in an upcoming action comedy Never Too Old to Die which has been attached to Amazon Studios. The script will be penned by Brian Otting.

The film will be backed by Sylvester along with Balboa Productions' Braden Aftergood.  Never Too Old to Die will revolve around a murder that mysteriously takes place inside a retirement home for spies, instigating a Cold War veteran to find the killer who is living among them.

The upcoming project will be the first that comes under Sylvester and Brian's multi-year, first-look deal with Amazon Studio, which will have projects that Sylvester write, direct, produce and star for the studio.  However, a director for Never Too Old to Die is yet to be attached.
