Scarlett Johansson does weather on 'Today' - watch
The star appeared on the NBC morning programme to promote Hitchcock, but found herself doing a live weather segment because anchor Al Roker came down with laryngitis.
"[This is] a dream come true," Johansson joked to Today presenters Matt Lauer and Savannah Guthrie as she read the forecasts.
Johansson even was able to utter Roker's catchphrase when sending viewers to their local forecast, saying: "Here's what's happening in your neck of the woods!"
The actress is making several appearances in New York City in promotion of Hitchcock, including an interview on The Late Show with David Letterman last week.
Hitchcock is now playing in the US and is released in the UK on February 3, 2013.
