I missed the Film Foundation’s restoration of Michael Curtiz’ “British Agent” (1934) at the TCM Classic Film Festival in April, so I was delighted to see it listed among the free screenings this weekend at the launch of the Film Society of Lincoln Center’s new Eleanor Bunin Munroe Film Center.

Though it resides with dozens of other obscurities on my DVR, I’ve never seen this romantic drama set in 1917 Moscow and starring Leslie Howard as a British diplomat and Kay Francis as Lenin’s secretary. Indeed, I had never even heard of it when were compiling our wishlist for TCM’s “Shadows of Russia” series.

According to old press releases quoted at the TCM website, 41 sets and 1,500 extras were employed for this 81-minute flick — and Jack Warner unsuccessfully petitioned the Soviet Union for permission to shoot background footage in that country. He certainly got more cooperation for Warners’ notoriously pro-Soviet “Mission to Moscow” a decade later.

Single standby tickets will be distributed 30 minutes before Sunday night’s 7:30 screening at the 150-seat Francesca Beale Theatre.
