EVERY MOVIE HAS A LESSON

In my opinion, very few actors have established themselves with their performance history to the point that their presence alone is an automatic sign of elevated quality towards an entire film.  Call it "street cred" on a casual level or "artistic integrity" on a professional level, but few actors and actresses are near-guarantees for solid and award-worthy performances every time they take on a role.  By my account, Academy Award winner Colin Firth has elevated to become one of those rare performers.  He's outstanding in everything he takes on, comedy or drama, and the films he chooses become better with him being there.
