This can be a strange and challenging experience for all involved.So, sometimes a little liquid courage goes a long way.

Slogans like 'Jäger: So you can be Jason Bourne ready' or 'Jäger: Helping Jason Bourne get it on since 2002' were ripe for the taking.

The Jägermeister shots clearly worked because the scene turned out quite well, as did as a whole.

As an actor you try to focus on your performance and your interaction with the other person, so perhaps some of the external elements fade into the background.

But as a director you are the one watching what is happening and having to judge it as a part of your film and give directions to the actors who are already feeling uncomfortable. Although porn directors do it all the time, so I suppose it just takes practice, or depends on personality.

- In The Bourne Identity, Matt Damon plays a spy who has forgotten everything except how to save his behind.

Damon's own survival instincts kicked in when he showed up for work in Paris and the script he approved had been replaced."It was unrecognizable in a way I was really uncomfortable with," he said in a recent interview.Maybe he had good reason: The previous two films in which Damon has played the leading man, the cowpoke romance All the Pretty Horses and the sub-par golf fantasy The Legend of Bagger Vance, averaged just more than million in ticket sales.But he insisted he feels no pressure to rustle-up more box-office bucks. "All the Pretty Horses was an unqualified failure, and yet it was my favorite movie I've ever worked on."In the midst of one of his busiest career stretches, Damon has found love with a regular gal. That's about all the responsibility I can handle right now."His connection with a woman who doesn't carry a SAG card makes sense.Director: Neill Blomkamp A hugely talented but socially isolated computer operator is tasked by Management to prove the Zero Theorem: that the universe ends as nothing, rendering life meaningless.
