Probably only works for hardcore Marx Brothers fans.

At the beginning of Groucho Returns, actor Frank Ferrante introduces himself to the audience as a former painfully shy kid who learned how to open up to the world by watching A Day at the Races. As he slathers black greasepaint on his eyebrows and upper lip, Ferrante explains that Groucho Marx provided him with a template for confidence, a persona he could adopt to relate to the world. Speaking as someone who fell in love with the Marx brothers as an awkward teen, I can certainly attest to the power of Groucho as a role model: When youโ€™re Groucho, the whole world is your straight man and youโ€™re the spinning funnel of gleeful chaos at the middle of everything.

Ferrante grabbed hold of Groucho and never let go; Grouchoโ€™s son, Arthur, hired him out of college to star as his father in a biographical revue. Ferrante has been playing Groucho ever since, for three decades now. And for the third summer in a row, heโ€™s come to ACT Theatre with Groucho Returns, a cabaret-style one-man show starring Ferrante doing his time-tested Groucho impersonation.

The show follows three threads. First, Ferrante relates Grouchoโ€™s life in a series of anecdotesโ€”the way his mother decimated his self-esteem to coax him on to fame and fortune, the way the Marx Brothers got their nicknames, and so on. Second, Ferrante performs a greatest-hits medley of Groucho songs (โ€œWhatever It Is, Iโ€™m Against It,โ€ โ€œLydia the Tattooed Ladyโ€) and routines from Marx Brothers movies. Third, Ferrante riffs with the audience in character as Groucho; he keeps it witty and light, but if interactive theater gives you hives, youโ€™ll want to keep far away from this show.

As impersonations, the anecdotes and the routines are very successful. Ferrante obviously knows his stuff; heโ€™s got to be the worldโ€™s foremost expert on Marxโ€™s mannerisms. But the whole thing about Groucho is that heโ€™s nobody without someoneโ€”a Marx Brother, a self-important goon, a determinedly plain schoolteacher on You Bet Your Lifeโ€”to bounce off of. And it takes a while to adjust to seeing Grouchoโ€™s gestures (especially the way he juts the tip of his tongue out of his mouth when heโ€™s feeling particularly cheeky) in the flesh a few feet from your face when youโ€™re used to seeing them on a movie screen. Though Groucho honed his craft on the vaudeville stage, his film mannerisms donโ€™t quite read the same way when brought back to the theater. Theyโ€™re a little creepier.

When Ferrante has someone to react to, heโ€™s at his best. Local pianist Mark Rabe is the straight man and the musical accompaniment, and he acquits himself capably. Ferrante tosses barbs Rabeโ€™s wayโ€”somehow, nothing sounds more insulting than someone with a Groucho Marx voice calling you โ€œworld-famousโ€โ€”and Rabe simply absorbs them with a slump-shouldered dignity.

The liveliest bits come when Ferrante is left to his own devices with the audience. Itโ€™s a fairly simple working-the-room framework: Someone who has the misfortune of momentarily crossing his arms when Ferrante notices him is lampooned for the next 90 minutes as a bitter person whoโ€™s mentally checked out. Ferrante praises another man for โ€œwearing your best shorts to the show.โ€ He hit on a woman named Barbara relentlessly. On the night I attended, the room was mostly made up of gray-haired couples (some of whom, we discovered, had been married for 50 or 60 years) and a handful of sweet, nerdy preteen boysโ€”both groups howled as Ferrante mocked the โ€œmotley crewโ€ who came out to see him in this โ€œdungeon in Seattle, of all places.โ€ The more Ferrante worked the room, the funnier he got.

(Full disclosure: In nearly a decade reviewing plays for The Stranger, I was involved in audience participation for the first time at Groucho Returns. Ferrante asked about my notebook, and I said I was reviewing the play for The Stranger. He recoiled in what seemed like genuine fear, chastised me for coming on preview nightโ€”though the theater had given me permission to attendโ€”and praised one of the boys in attendance for having โ€œmore culture in him than an entire issue of The Stranger.โ€ He asked me the difference between critics and reviewersโ€”โ€œI presume critics make more money,โ€ I answeredโ€”and he told me that the Seattle Weekly loved his show last year. As someone whoโ€™s lived in fear of audience participation his whole life, it wasnโ€™t as bad as I feared.)

Groucho Returns probably only works for hardcore Marx Brothers fans, and even then itโ€™s not in itself a wholly satisfying experience. I laughed a fair amount and I appreciated Ferranteโ€™s spot-on impersonation, but the evening left me with a bone-deep desire to watch some Marx Brothers movies to scratch the itch that all the Groucho talk inspired in me. Turns out, when youโ€™re in the mood for Grouchoโ€™s special mix of wit and low culture and human cartoonishness, you can accept no substitutes. recommended
