Question: what is the age difference between jo and professor bhaer?
Answer: For one thing, Garrel's casting tightens the gap between Jo and Bhaer's respective years considerably. Alcott's book never specifies Bhaer's age, only describing him as 'middle-aged'. We know that Jo is 30 at the end of Little Women when Bhaer proposes after delivering the finished copy of Jo's novel. In the rain.
