I’ve heard or read that Hugh Laurie is having some problems in his leg by having to fake a gimp all the time by acting as House. I think I’ve got a solution, it’s not cheap but it’s cheaper than having the actor not being able to perform anymore:

Build a set that is a mirror of the current sets down to the text in the doors, then have Hugh Laurie gimp with the other leg, film everything like than and then mirror the result, so that Hugh Laurie can balance out which side he’s straining.

I bet that it would also be a very interesting acting challenge.
