When Eddie Murphy crashed the Hollywood scene, after his breakout success on SNL, he went through a period where he could do no wrong. Of his first four movies, three went on to box office success. We just couldn't get enough.
For almost three years he had a nonstop of string of crowd pleasing hits, 48 Hours, Trading Places and Beverly Hills Cop -- all of which generated their own catchphrases.
I suspect this was because Murphy was less self aware of his performances, which made them genuine and less rehearsed.
Looking good, Billy Ray!
Feeling good, Louis!
