"Have beens" meeting

[Bushwhacker]

To express that a lot of old action movie stars from the past two decades meet somewhere, do you find correct to express it as "A meeting of the last two decades action-movie "have beens?
A movie "have-been" meeting? Is "have-beens" possible?

If not, how would you say it?

Thank You

NOT A TEACHER

I believe that the term is has-been.

A meeting of two action-movie has-beens.

I believe that the term is very rude and hurtful. It means that

you were once somebody important; now you are no longer

wanted (in the movies, etc.).
