Rovello played Richie Brown, the son of Julianne Moore's character, in the 2002 drama film The Hours. Scotland on Sunday noted that he gave a "very striking appearance... as Moore's sensitive son", while The Charleston Gazette called Rovello one of the film's two "talented, young newcomers" alongside Sophie Wyburd. For his work in the film, Rovello was nominated for Best Performance by a Youth in a Leading or Supporting Role – Male at the Phoenix Film Critics Society Awards in 2002, ultimately losing to Nicholas Hoult for the film About a Boy.

In 2005, Rovello co-starred in the Steve Buscemi-directed film Lonesome Jim with Casey Affleck and Liv Tyler. In 2013, Rovello appeared in the short film Socks & Robbers as the character Chester. Its creator Ben Fraternale, a senior at the University of Maryland, had known Rovello "for years and was really excited to highlight him. He was a child actor who had been out of work for quite some time, so featuring him and his talents in Socks & Robbers was great to see." Rovello has also appeared in the American television series Days of Our Lives, Sex And The City, and One Life to Live.
