That was from the movie Braveheart. Longshanks’ sissy son declared Philip to be his royal counsel as things were falling apart. Philip was just as fruity, and Longshanks took him aside to ask for “advice” before throwing out the window.
I’ve only seen parts of Braveheart. Another movie I need to see.
I wonder if that particular incident was part of the inspiration for the “Swamp Castle sequence” (where the dad (Palin) tosses his son Herbert (Jones) out the window and adopts Lancelot (Cleese) as his son instead) in Monty Python and the Holy Grail?
