Doctor Who ranted, making a sort of drama (3,6)
I believe the answer is:
Here is my best explanation:
'a sort of drama' is the definition.
'doctor who ranted' is the wordplay.
'doctor' indicates anagramming the letters.
'whoranted' with letters rearranged gives 'twohander'.
'making' is the link.
(Another definition for two-hander that I've seen is "Play for a pair of actors".)
