McGovern is both playwright and leading actress in Ava at the Geffen Playhouse.

The stars of the Golden Age of Hollywood are more image than substance, more enigma than knowable.

She’s mesmerizing when Gardner’s tempestuous nature and legendary temper explode in sudden and unexpected ways.

This is also enhanced by the fact that McGovern is never giving us an imitation of Gardner.

Yes, she models the transatlantic clipped tones of mid-century stars, tinged with Gardner’s North Carolina roots.

And she carries herself with Gardner’s immense self-possession.

Ganis has an even more difficult task, and he not only rises to but exceeds the challenge.

Playing one of these men is a tall order, much less all four.

It’s a strange magic trick, a performance miles more interesting than oft-Oscar-winning biopic roles aided by prosthetics.

Still, the center ofAva,as a character and a play, will not hold.

That’s at least somewhat intentional.

Avahas two electric actors at its center, but it lacks cohesion.

Gardner never believed herself a great actress and was rarely given material to prove herself otherwise.
