the boom mike issue
One of the reviewers said that the visible boom mike was not a mistake, but an intentional satirical comment by the filmmakers. Interesting theory, but simply not true. I've seen Lord Love a Duck on the big screen, run by a qualified projectionist, and the booms are not visible.
LLAD was intended to be shown widescreen. While a super wide process like Cinemascope creates a wide image on a square film frame by use of an anamorphic lens, a more moderate widescreen film such as LLAD would have simply composed the center of the frame for widescreen, with instructions to the projectionist to matte off the top and bottom of the frame when the film is shown.
In the earlier days of tv and home video, no one wanted letterboxing, so the film had to be shown "square". In the case of a Cinemascope film, this meant centering in on a portion of the wide image (pan and scan). With a film like LLAD, it meant going back to the original print and showing the whole thing without matting off top or bottom (open matte). The result was sometimes visible boom mikes and floor cables that were not meant to be seen. Examples can be seen in the early video releases of Walking Tall, Pee-Wee's Big Adventure, the Chevy Chase comedy Modern Problems, and John Cassavetes' Husbands, just to name a few off the top of my head. The boom mikes in Lord Love a Duck are not meant to be seen. The film is indeed ahead of its time, but it wasn't quite THAT post-modern.
