(CBS News) A new restoration of legendary actor Robert De Niro's 1982 film "The King of Comedy" is set to close this year's Tribeca Film Festival. Appearing on "CBS This Morning" alongside Tribeca co-founder Jane Rosenthal Thursday, De Niro joked that he's surprised the film is already in need of touching up.

"That's kind of scary," he said. "But I'm happy. I'm looking forward to it. And it will be interesting because it reminds me of that period -- also just reminds me of things outside of the movie event in my life at that time -- and so it will be kind of fun. I haven't seen the movie in decades."

De Niro and Rosenthal, a filmmaker, co-founded the festival in 2001 as a response to the September 11th attacks on the World Trade Center. Their goal was to celebrate film, revive New York City's economy and attract visitors back to Lower Manhattan.

Now, 12 years later, the festival has screened over 1,400 films from over 80 different countries. It has also attracted an international audience of more than four million attendees and generated and estimated $750 million for the City of New York.

This year's festival runs through April 28.
