As soon as Anderson Cooper lets the 'We Bought a Zoo' stars take over his talk show, Scarlett makes a mistake by handing out her mic to one audience.

Scarlett Johansson and Matt Damon have got a short co-hosting class from Anderson Cooper when visiting his talk show "Anderson". Coming as guests for the upcoming Wednesday, December 21 episode, the "We Bought a Zoo" stars give a hand by fielding questions from fans.

Before he lets Scarlett and Matt co-host, Anderson jokingly says that the pressure is on since Hugh Jackman had done this before and he did it great. Soon after they take over the show, the Natasha Romanoff of "Iron Man 2" makes a mistake by letting a man from the audience hold the mic, forcing Anderson to correct it.

Scarlett and Matt are joined by other "We Bought a Zoo" cast members, including Elle Fanning, and the movie director Cameron Crowe for the interview. Beside talking about the film, "The Avengers" beauty will reveal which former co-star was the best kisser, while the "Contagion" hunk will open up about the challenges of raising four daughters.
