How is Eddie Murphy still getting lead rolls in huge movies?

Usually in Hollywood, if you star in a couple of big budget movies that tank, you usually don’t get another chance unless you do a couple of indie/medium budget movies to come back on top.
How is it that Eddie Murphy, despite having numerous box office failures in the past few years, still manages to get the big budget leading rolls?
I understand that he was a huge star, and has had a bunch of successful movies. Is he putting his own money/studio funds to back up the costs, or is a studio still putting faith in him?
tnx
