Challenge us with a non-famous line from a movie

Inglourious Basterds?

No, one of the Crocodile Dundee movies IIRC, but I can’t remember which one…

Inviter, motions to chair to the guest ( enthusiastically )

Sit, sit, sit sit!

Invitee:

Must I do so four times?

Still haven’t seen a guess for this one:

“You get these sudden urges and then you come up with warthogs and rhinoceroses!”

I knew I’d heard that, I could almost pull in the actor’s voice, but no, I had to look it up, what a great movie.

Yep, Dundee 2. Don't need a gun when you have a Donk - Crocodile Dundee 2 - YouTube

“Is it safe?”

(Two possibilities here. As I watched the more recent movie, I kept thinking of the older movie.)

Lawrence Olivier in Marathon Man

Yes, but do you know the other movie?

The Fellowship of the Ring?

Right

Also Aladdin. With the next line being:

“Yeah; do you trust me?”

I remember the line was parodied in a comedy. One of the Naked Gun/ Hot Shots series, but I don 't recall which one.

“If he gets a word in, it’ll be a major Italian victory.”

Operation Mincemeat?

I’m afraid not.

“If he gets a word in, it’ll be a major Italian victory.”

My Fair Lady ?

Casablanca

Casablanca is correct.

“Woman, you’re driving me crazy. Didn’t he have a gun?”
“Well, yeah, he had a gun.”
“Well?”
“I took it from him and called the police.”
“Oh, you just took it to the police… just like that. And then I suppose you gave him tea.”
“Milk.”

“You get these sudden urges and then you come up with warthogs and rhinoceroses!”

The Gods Must Be Crazy

And a new one…

“It is alive.”

Hint: It’s not Frankenstein.
