While promoting her new movie 'Morning Glory,' in which she plays a TV morning show host, Diane Keaton temporarily takes over for Meredith Vieira and tries hosting 'Today' (weekdays, 7AM ET on NBC).

"Would you ever consider co-hosting with me?" Vieira asked.

"What?! Okay, well, look, here's the deal -- I don't think so, because, Meredith, let's face it, I'd have to read, which is hard for me," said Keaton, gesturing to the teleprompter.

But Vieira insists. So, Keaton peers into the teleprompter and segues into a commercial break, doing a fairly impressive job in the process.
