* Carmen is a famous opera by Georges Bizet, which has been performed countless times with different casts.
* Columbo is a detective series that ran from 1968 to 2003 with Peter Falk playing the titular detective.
It's possible you're thinking of a different production or you've made a mistake in the title.
Could you please clarify your question? Perhaps you meant:
* A specific production of the Carmen opera from 2011?
* A specific episode of Columbo from 2011?
* A different movie or TV show entirely?
Once you provide more information, I can help you find the cast information.
