"Being horrible in a big film is a quicker nosedive than doing an obscure film and making no money"

This quote by Renee Zellweger talks to the risks of taking on a huge film role. She is suggesting that if a star handles a significant function in a big film and performs inadequately, the effects can be more serious than if they take on a smaller sized, less popular film and make no money. This is since the actor's efficiency in the huge film will be seen by a much bigger audience, and the failure to deliver a great efficiency will be more commonly seen. The star's track record could suffer more from a bad performance in a big movie than from a bad performance in an unknown film. Zellweger is warning actors to be mindful when taking on a significant role in a big film, as the repercussions of a bad performance could be more damaging than not making any money from a smaller sized film.
