"I think when you're doing a lead role, there is so much more pressure. If you fail, not only do you fail, but everybody else fails, too. As opposed to when it's a supporting role and it's only you that sucked"

Leelee Sobieski's quote talks to the pressure of handling a lead function in a movie. When an actor handles a lead function, they are accountable for the success of the whole project. If they stop working, it is not only their own failure, but the failure of the entire cast and crew. On the other hand, if an actor handles a supporting role, they are only accountable for their own performance. If they stop working, it is only their own failure and not the failure of the whole task. This quote highlights the tremendous pressure that features taking on a lead role in a film, and the significance of providing an effective performance.
