From the many books I have read I do know Philip was very angry about his children not taking his name. I think if he pursued this legally, he would have won his case. And, I think him finding a role for him to play once his wife became queen was difficult due to the obstruction of palace courtiers.
I think Matt Smith played him too whiny.
One scene that I do not think happened was Philip asking the Queen that he not kneel to her at the coronation. Philip was from a royal house from Greece and Denmark so he would have known his role and what he would need to do. I believe this scene was made up to create drama.
