Jerry O'Connell had no problem dressing up in a space suit for his role in Mission to Mars, but there was no way that he was going to get into an aircraft commonly referred to by astronauts as the "vomit comet."

"There was talk about doing the vomit comet," the actor tells TV Guide Online. "But I don't go on planes that are nicknamed 'the vomit comet.' I don't do things like that. I don't like the left lane on the freeway, I don't like vomiting on myself. It's a little peeve I have."

On the other hand, O'Connell says he loved every minute he spent in his space suit. "To throw on a NASA-made space suit with an American flag on the arm — it doesn't get any better than that. That's every little boy's dream come true."

O'Connell was so comfortable in his suit, in fact, that he occasionally nodded off while wearing it — which isn't all that surprising given that he had to hang from wires for eight hours at a time in the thing.

"I was out cold half the time. I had climate control in the suit," he adds. "It was a very comforting, womb-like experience."
