It's possible you're thinking of a specific movie or TV show where Jim Sturgess played a character who interacted with a character named Mickey.
To help me understand your question better, could you please provide more context?
For example, could you tell me:
* What movie or TV show are you referring to?
* What is the name of the character Jim Sturgess played?
* What is the relationship between the two characters?
Once I have this information, I can give you a more accurate answer.
