The title ruler in Shakespeare's King Richard II is a psychologist's dream - there must be enough material to write an award-winning casebook.
Richard II exhibits paranoia, has a tendency to manic depression, but is also highly intelligent and cultured.
So when Jonathan Douglas - producer of RTHK Radio 4's Art Beat - was told he was 'just right' for the lead role in the forthcoming production by Queen's Cafe Theatre, it was fortunate he took it as a compliment.
'Richard is a complex, poetic character, flawed but with an incredible imagination,' he said.
So is this a character description of Douglas himself? 'Yes, it definitely struck a chord, though it is important to suspend oneself. I become Richard more than he becomes me,' he added.
The play revolves around Richard's voyage of self-destruction and the transfer of power from Richard as child king to Richard the adult monarch, who is being forced to relinquish his crown to his cousin Bolingbroke.
The director, Linda Dunn, a linchpin of Hong Kong amateur dramatics, said she had always wanted to direct a Shakespeare play but was keen that it should be one of the lesser known ones.
