Usually, when people think of Harrison Ford, they get a warm, fuzzy feeling. They think of years past... Star Wars marathons, seeing Indiana Jones on the big screen, dressing up like an Amish guy for Halloween because you loved Witness so much...

However, as nice a guy as Harrison might seem to be in all the Barbara Walters interviews, he's apparently not such an easy guy to work with when making an ad. Even an ad to promote an environmental cause he's involved with.

BBDO NY is currently developing a campaign with the actor, and he has attempted to rewrite the creatives' scripts himself... multiple times.

He's finicky about scripts, mainly because he's so concerned about his voice and face being attached to the project. Not because the scripts or concepts are bad... but because... well, he's a celebrity and celebs apparently have earned the right to be difficult.

He's apparently so finicky, in fact, that his demanded changes completely decimated a scheduled shoot in Latin America to get the campaign rolling.

Oh, Harrison. Just go with it. BBDO does great work.
