Weeds star Mary-Louise Parker has joined the cast of R.I.P.D. for Universal Pictures.

The project is based on the graphic novel by Peter M. Lenkov and centers on a police unit comprised of cops killed in the line of duty entitled the Rest in Peace Department. Mary-Louise Parker will play the head of R.I.P.D., who must explain the unit to a newcomer played by Ryan Reynolds. It is also said that Jodie Foster had shown interest in the part before eventually passing.

Robert Schwentke is directing R.I.P.D. from an adapted screenplay by Phil Hay and Matt Manfredi. It isn't known when production will begin on R.I.P.D. yet.
