•Did you guys know each other before doing this film?
DAMON: We'd met at a couple of events and lied and told each other we really liked each other's work.
KINNEAR: The next time we met, it was to go into a room...
DAMON:...and take our clothes off...
KINNEAR:...and get harnessed together and get the feel of what it was going to be like for the next four months.
•That sounds pretty intimate.
DAMON: It was an accelerated courtship.
KINNEAR: No drink, no dinner. It was straight to the stuff.
•You even had to go to the bathroom together?
DAMON: For guys it's a lot easier, because we grow up going into urinals. So you're used to having guys around you. You're just not used to them rubbing up against you and...
KINNEAR:...and blowing in your ear, which I would do on occasion.
DAMON: Greg said it was like going to the bathroom at the end of a Springsteen concert...
KINNEAR:...when there's only one working urinal in the whole stadium.
•If you were women, you'd have told each other all your secrets.
DAMON: There weren't many secrets by the end of four months.
KINNEAR: It will all be in my book about Matt.
•Would you trip each other as you walked in that thing?
•KINNEAR: No! Any act of violence against the other is an act against yourself. We were very kind to each other.... If you're going to do a conjoined twin film, I would recommend being attached to Matt Damon as much as anybody. Except Halle Berry.
