10 Recent Movie Performances Even More Impressive When You Know The Truth

Having to step into the shoes of one of the most iconic figures in musical theatre history in a remake of one of the most adored cinematic adaptations of all time would likely be enough to leave most humans resembling an anxious puddle in the corner of a movie set.

But taking that pressure-filled scenario up a few notches in the making of Stephen Spielberg's recent critically acclaimed spin on West Side Story was the fact that Rachel Zegler had some rather high-profile front-row audience members when it came time for her to warble Maria's legendary "I Feel Pretty" number.

In one of his three no doubt jaw-dropping set visits, the immortal Bruce Springsteen was present for Zegler's live rendition of the song, with iconic composer Stephen Sondheim - who actually wrote the lyrics for the number in question - also sitting alongside Brucie for the Maria star's performance.

Understandably noting how she was star-struck to the point of not being able to go over and say hello to the unmistakable icons and two of her all-time heroes, the whole experience was enough to make Zegler feel insanely "nervous", never mind pretty.
