PLEASE READ THIS - This is Irish McCalla's very brief scene from the 1959 B-grade war drama, "Five Gates To Hell". She is also the nun walking to the tent in the opening credits. I have uploaded this clip to embed in my web page about that film:

The film, which is set in Indo-China during the escalating conflict in that region, was the directorial debut of the author, James Clavell. It starred Delores Michaels as Athena; Patricia Owens as Joy; Neville Brand as Chen Pamok; Ken Scott as Dr John Richter; Nobu McCarthy as Chioko; Nancy Kulp as Susette; and Irish McCalla, of "Sheena Queen of the Jungle" fame, in a brief role as Sister Magdalena.
