After its success onstage, My Fair Lady was adapted into a film, starring Audrey Hepburn as Doolittle, which won eight Oscars awards in 1965.

Moss says that although the musical is 60 years old, it presents new challenges each time it is produced.

"Its story and characters are so well written and defined that finding new 'life' for the characters and interesting ways to present the story is a great joy and challenge for a director. But the authors, including Shaw, have provided a great wealth of material to draw from," he says.

Songs written by the lyricist Lerner and composer Loewe in the musical, including The Rain in Spain, Wouldn't It Be Lovely and Get Me to the Church on Time, are clever, witty and very specific to each moment. The music is emotionally telling and fits each characters' needs, says Moss.

"The proof is that 60 years later, most of the world is still singing or recognizing these wonderful songs," he adds.

In the latest version of the musical, Sarah Cetrulo makes her international debut by starring as Doolittle. The linguistics professor Higgins is played by Chris Carsten.

The director believes that the musical's longevity also lies in its story, which could happen in real life, especially today, as more and more women, like Doolittle, look to improve themselves and move to better places in their lives.

"Each audience member can find their own message in this story. But I hope, at least, to present the story in an entertaining way, so that the tale of a smart young woman who tries to improve her situation in life can clearly be seen and enjoyed by all," says Moss.
