Regent Square

8 p.m. "Cherry Blossoms" -- Yet another reminder that man plans and God laughs, as a middle-age German couple go on vacation when the wife learns her husband is ill.

Regent Square

8 p.m. "The Passion of Joan of Arc" with the Bach Choir -- As our Nov. 6 review ('The Passion of Joan of Arc') noted, many consider this 1928 silent film one of the 10 greatest movies ever made. Just as many regard its title-role performance as the single most inspired in film history -- by a woman who never set foot in front of a camera again.

Harris

7:30 p.m. "How About You" -- Ireland provides the backdrop for this movie pitting four grumpy oldsters against a newcomer in charge of a residential home at Christmas.

9:30 p.m. "The Korean" -- Pittsburgh places and faces figure prominently in Thomas Dixon's debut feature about the perils of being mixed up with a mobster or his cleaner, the title character.

Melwood

8 p.m. "Mock Up On Mu" -- Hybrid of spy, sci-fi, Western and horror movies, from experimental filmmaker Craig Baldwin.

Regent Square

2 p.m. "One Day You'll Understand" -- Story of a Frenchman's search for the truth about his Jewish parents' wartime decisions. With Jeanne Moreau.

4:30 p.m. "Tamas" -- The title refers to Tamas Szilagyi, a much-heralded history teacher at The Kiski School in Saltsburg, Indiana County. His students included David Conrad, the actor turned documentary maker who accompanied Szilagyi back to Hungary for the 50th anniversary of the revolution.

8 p.m. "Pittsburgh Reframed (at 250)" -- Program of new shorts based on a promotional 1958 film.
