Dan Aykroyd: 'Ghostbusters' Reboot Is 'Comic Role of a Lifetime'

Plus: His Yogi Bear co-star Justin Timberlake talks about the injury he sustained on the set of Now last week.

Dan Aykroyd is pumped about the Ghostbusters reboot.

"Great script, and [the writers] have written a part for Bill Murray that is a comic role of a lifetime," Aykroyd told Entertainment Tonight of his co-star, who plays Dr. Peter Venkman. "We've got the material. It's in the bag. Now it's just a matter of doing what you do when you produce a movie."

His Yogi Bear co-star, Justin Timberlake, also opened up to ET about hurting his left calf muscle while doing a stunt on the set of Now last week.

""My calf is ... it's not that bad," Timberlake joked. "It'll be fine. It's not irreversibly damaged. ... I was just on set and I hurt it. I wish I had a way better story about how I got into this Bruce Lee, Kung Fu fight with someone and 'you should see the other guy,' but unfortunately I did it to myself."
