Five-Man Band/Film

The Five-Man Band is a group of characters whose members fall into archetypes which all complement one another. They are a very specific team with skills that contribute to the group in a unique way. Here are some places where the trope occurs in film:

A-E
Atlantis the Lost Empire

* Note: Jack Burton thinks he's the hero and Wang Chi is his lancer

* Note: Lampy is The Chick in German version.

F-J
* Note: Louis Tully was the Sixth Ranger in Ghostbusters II.

Grease:

* Note: N.B. Saito's the sixth man in this group, and is referred to as "The Tourist." At least, Ariadne is more positive aspects of this trope.

Alternately:

The Indiana Jones films:

* Please note: That Indy and Mutt both feature elements of both The Hero and The Lancer, and can arguably be traded back and forth between roles as the movie progresses.

P-T
Rebuild of Evangelion seems to be building up to this, although a lack of interaction between pilots makes it difficult to determine the exacts yet, and it is possible an additional pilot will be introduced to further mix things up.

* Note: Barbie is Molly's doll.

* Note: Louis and Billy Ray both possess traits of The Hero and The Lancer interchangeably.
