When the Hollywood Bowl is transformed into 1950s New York this weekend for a revival of “Guys and Dolls,” it will be the culmination of a rapid-fire two weeks of preparation by all-star cast that includes Jessica Biel, Brian Stokes Mitchell, Scott Bakula, Ellen Green and Beau Bridges.

Also in the ensemble, having crammed months’ worth of rehearsal time into just a few days, will be two Los Angeles-based dancers, both 22-year-old Puerto Rico natives, who remain floored at the opportunity that the production has provided them with so early in their careers.

“I have to tell you that I am having the time of my life doing this show,” said Oskar Rodriguez in an interview early this week, during a break from rehearsals at the Bowl. “I wasn’t sure I was what they were looking for in the audition, I almost walked out because I thought I was too young, but I’m so glad that I stayed.”

Born in San Juan, Rodriguez has been performing since he was 16, and already counts the likes of Ednita Nazario, Manny Manuel and Thalía among his recent collaborators. An L.A. transplant via New York City, his film credits include “Dirty Dancing: Havana Nights” and 2007s “Cougar Club.” The finishing touches are now being put on his latest project, a film with Mexican director Emilio Vega that will debut later this year as part of a groundbreaking Latino Film Festival in Lynwood.

Rodriguez, who acknowledges that he had to learn English in a very short period of time, sees clear parallels between the character he plays in “Guys and Dolls” and his own journey to America from his native island. He isn’t just playing a young kid arriving in New York, looking up at the big lights and being wowed: “That was me at one point,” Rodriguez said. “That doesn’t happen to a lot of young kids from Puerto Rico.”

Working with cast members he’s only heard about or read about or watched on the big screen, Rodriguez said he’s very impressed with how humble and dedicated people are on the set.

“It’s been so a wonderful experience, just to meet some of these people, to see how they are just regular people like you and me, and then watch them work,” said Rodriguez. “It’s amazing to know that here I am on stage with people that I’ve admired since I was a little kid, and I’m coming from this little town in Puerto Rico, and I’m being given the opportunity to perform alongside them. It’s overwhelming.”

Alongside Rodriguez, also portraying a dancer in a pivotal scene set inside a Havana nightclub, is Angelo Rivera. A longtime admirer of “Guys and Dolls” — which premiered in 1950, ran for 1,200 performances, and won 15 Tony awards — he is especially excited about the creative energy that his director is bringing to the production.

“This show set the stage, literally, for musicals,” said Rivera, who also portrays a craps shooter in the show, and has appeared on Broadway in “The Lion King,” among other credits. “‘Guys and Dolls’ has always been an all-time Broadway favorite. This is my first time doing this show, but I can see why performers love doing this show over and over again. But I will tell you something — Richard Jay Alexander has brought something special to this version.”

Watching the all-star cast meld together for the show has also been an awe-inspiring experience for Rivera. “It’s been both challenging and wonderful at the same time,” said Rivera, referring to the short-time frame the entire cast was given to rehears before the show’s July 31 opening. “Still, there are some phenomenal people working on this show, and everyone works together. It’s amazing to watch it all come together in such a short period of time, so that’s why it’s exciting … seeing the caliber of talent involved with the show, then watching everyone come together and work their magic, it’s beyond words.”

“Are you kidding me? Right now, I feel like I’m ready for anything,” he said. “Watching this show come together and watching all of these people, has inspired me … so right now, well maybe not this weekend, I feel like anything at this point can be thrown at me and I’ll be ready for it.”

“Guys and Dolls” in Concert opens July 31 with a show at 8 p.m. There is a second show Aug. 1 at 8:30 p.m. and a third show on Aug. 2, at 7:30 p.m. The Hollywood Bowl is located at 2301 N. Highland Ave., Hollywood. For more information or for tickets, call (323) 850-2050.
