Guess the Movie

[Swatopluk]

The Third Man? (quite long ago that I have seen it but the picture reminds me of one scene).

[Aggie]

The lake monster hint: The villain is named Hogofogo, the Canadian monster is Ogopogo

Suspected as much, not that it helped. 

I think I actually did see Ogie around Christmastime (parents now live near Okanagan Lake); at the least, I saw what is typically photographed in a 'sighting'.  I wasn't particularly impressed, but who knows?

[Opsa]

The lady's clothes and hairdo looks more like the sixties to me. Very stylish. My, but they're serious.

They seem to be at a meeting. The reading of a will, perhaps?

[beagle]

The room looks sort of Café Royal, and the bloke at the back right almost looks like Patrick Macnee.

Is it "The Avengers meet Wallace and Gromit"?

[goat starer]

I enjoyed that one. Especially the bit where Emma Peel fights the plastacine robot sheep rusling dog.

[beagle]

It always amazed me how often they found excuses to dress her in leather and give her a whip.

...

...

What were we talking about? My mind wandered off again. I don't see you guessing, by the way.

[Opsa]

It's obviously some kind of who-done-it, as the guilty butler in the background seems to be sidlingto the door.

[beagle]

I think it's one of Griffin's home movies and she is in fact on the stage in front of them singing her karaoke version of "My Way".

[goat starer]

I can seen Griffin living in a house like that.

[Griffin NoName]

House, yes, chairs like that, never. The karaoke is off screen bottom right.

Guess on decade was right.

Let's see how you get on in the bedroom.

[goat starer]

looks like I will get on JUST FINE in the bedroom thanks 

[Swatopluk]

Now I am sure that I don't know the movie (at least not seen it).

[Griffin NoName]

Ah but I am being devious. I have seen the movie and I'd never get it from these particular stills.

Let's have a closer look at some of the guests:

[Swatopluk]

Drat! This old monitor and the lighting in this room spoil any details.
Wild guess: Is that Katherine Hepburn on the left? (and is any dinner involved? [if the 'guests' are meant as a hint])
Or is it something about felines with hight temperature metal contacts

OK those one are already in color, so probably a miss. (and the second is not from the 60ies)

No idea

[Griffin NoName]

Just for Swato we'll zoom in on the lady. It's not Katherine Hepburn. Not even the same nationality. And yes Guests is a hint.
