The pilots look worried, Han frequently shows signs of disbelief at what he is hearing.

Of course, thats before Han joins the rebellion, and Luke becomes a full-fledged Jedi....

Yeah, the whole point of the cavalier way everyone is treating the briefing is that they ARE confident. They don't know the Emperor has set a trap in motion. By making them look all solemn and serious, it ruins that effect. And I mean, it's not like they're cracking fart jokes while talking about taking down the Death Star.
