While Buenos Aires-born Roger is new to Broadway, this production made her a star in London, where it originated in 2006. At the risk of sounding harsh, the actress is physically unprepossessing – short and beaky – not to mention occasionally shrill in the vocal department. But she acts the hell out of the role. ... The other bit of headline casting is Ricky Martin as Che. Moving away from the original production’s clear allusions to Che Guevara, he appears here as an enigmatic peasant worker who serves as the bio-musical’s narrator and its voice of skepticism, seeing the beatified “Santa Evita” for the ravenous spotlight-seeker she really is. His dramatic presence could be more aggressive, but Martin’s Latin-pop vocals are a smooth fit for the role, and his relaxed charm and dreamboat looks will yield few complaints. Fans eager for him to bust some serious dance moves have to wait until midway through Act II, but he eventually turns on the trademark sizzle.
