Well, in Akbar's case I can help. I recommend the following documentaries to learn more about Akbar.
1. The Story of India by the BBC. Episode-5 The Meeting of Two Oceans
The section on Akbar is very detailed and you get to know many new things about his life and times.
2. Bharat Ek Khoj
There are two episodes on Akbar. Episode 32 and 33
Both the above mentioned documentaries are available on youtube and you must see them.
If you have any others suggestions please tell.
