 Filming went a few weeks over schedule, which in turn caused some  conflicts with _Casablanca (1942)_ (qv), which also starred  Claude Rains (qv) and Paul Henreid (qv). Rains finished work on  this movie June 3rd in 1942 and did his first scene on  _Casablanca (1942)_ (qv) at 10:30 the next morning.
