Not sure if this is a blooper, but oddly in some of the earlier scenes in
How to Succeed at Murder, 'Henrietta', when shot from behind, is being played by a living actress. She even twitches her thumb. This is before the big reveal that she is actually a puppet, so in a way it's conning the viewer. And before anyone says it, I know these things weren't made with the knowledge that one day they'd be scrutinised in high definition on DVD, but even so, it's still a rather misleading thing to do.
This is NO puppet !!
At a guess I'd say it's this woman ...
