Hopefully I haven't used this one before -

Hints:
70s
Italian film
Female Filmmaker

Pics: One of the greatest comic scenes in cinema. NSFW!!

Looks like an apricot to me!

Hint:

Was remade into a less impressive US comedy starring one of the 70s biggest stand-up comics.

"The Seduction of Mimi", by Lina Wertmüller?

Was remade as "Which way is up?", with Richard Pryor.

Correct!

Highly recommended comedy (with political overtones) if you haven't seen it and Lina Wertmuller is really an unsung hero for that era.

To which movie belongs this friendly Gentleman?

New hint:
Remember the gent from the first hint?
Well these two are after him to put him to eternal rest.

New hint:

Remember the two guys from the second hint?
Those are two of three brothers involved in making this movie (they also wrote the script).
The movie itself is (arguably?) one of the funniest movies ever.
Movie buffs usually love it.

New hint:

Remember the three brothers from the third hint?
Their family name is also a river in Nieuw Amsterdam.

And another hint:

Two famous quotes from the movie:

a) you're doomed!
b) what difference does it make?

3 Musketeers vs. Dracula?

Nope...sorry, maybe I should have mentioned this: Dracula is only an hors d'oeuvre to the main story...

New hint:

There's a captain involved, which has nothing to do with Dee Snider, Pazuzu, or alternative rock.

Still no idea,...anyone?

Hm,...you guys make it hard for me to find clues that I can give you.

Well, then...here are some of the actors featured in the movie:

- Richard Donner
- John Larroquette
- Clint Walker

Seems cool but I have never seen it.

Well, as far as I am concerned, you don't have to have seen a movie to participate...if you know the name - just out with it. :)
