Several years ago, Brendan Gleeson and writer-director John Michael McDonagh scored a Sundance hit with the low-key dark comedy "The Guard."

Sundance 2014 finds them reuniting for more bleak laughs and some religious introspection in "Calvary," with "Bridesmaids" star Chris O'Dowd in tow.

The film's first trailer (above) gives you an idea of what to expect from the Bergman-esque tale of an idealistic priest (Gleeson) who finds himself seeing the world in a new light after receiving a death threat during a confession.

It also stars Irish comedian Dylan Moran, Kelly Reilly ("Flight"), Isaach de Bankolé ("The Limits of Control") and Aidan Gillen, so memorable on both "Game of Thrones" and "The Wire."

"Calvary" will be unveiled in the Premieres category at Sundance, which begins January 16.

"Calvary" doesn't yet have a U.S. release date, but will hit U.K. theaters on April 11.
