Which comedy film is this line from? “Fire at will! – Which one’s will!?”?

I remember this line being in a funny film, think it was some kind of parody film similar to Naked Gun. It was so long ago that I saw it though that I can’t remember what film it was. Tried searching the net and couldn’t find anything. Anyone know? Thanks

Bottom Live 3 Hooligan’s Island?

Here’s the clip. It’s at 8:49 minutes in.

That sounds like Independence Day with Will Smith,Jeff Goldblum and Bill Paxton.

Probably one of the Hot Shots movies among others. It’s a pretty common quote.

Three Stooges

I think this has been in a few.

It appeared in the old television series Dads Army I think..
