Dan Stevens also stars in David Midell’s earnest but tepid dramatization of a purported demonic possession case in 1928 Iowa.

Ashley Greene, Patricia Heaton and Abigail Cowen also appear in David Midell's entry in the overdone subgenre.

The Ritual” starring Al Pacino, Dan Stevens, Ashley Greene, and Patricia Heaton will be released in theaters on Friday, June 6.

The Al Pacino-led possession thriller purports to be based on the true story of the infamous 1928 exorcism of Emma Schmidt.
