They were great. There was a little bit of rivalry from scene to scene which helped the actual plot too - life mimicking art.
It was the old team coming back to show the new kids on the block how to do things... But they were great. Got on well with Emma who's very cool. Jason David Frank was cool to meet and work with too. We had fun on set - we'd always try and keep the set laughing yet efficient. I think we felt like we were the old boys - cause we were the oldest on set.
