A Lista de Adrian Messenger

I wanted to say something in praise of the masked star gimmick - something I haven't seen anyone else mention.

Rather than viewing the various "heavily made-up" characters as a spot the star contest, look at it from the other side and, suddenly, the gimmick becomes an ingenious way of covering up the killer - hiding him from the audience. Since the filmmakers knew they couldn't find a way to make a full head latex "invisible" to the audience, (and presumably didn't want to go with a completely other actor) they went the Purloined Letter route and threw in a bunch of such "spottable" characters to keep the audience from guessing which one was the killer.

Much like the movie The Spanish Prisoner - where every person seems somehow fakey UNTIL you watch from the viewpoint of "spot the scam" and realize the EVERYONE sounds fake (i.e., like they're scamming someone) so you CAN'T spot the con artists.

Brilliant, really. In both cases.
