Googling for 'Antinous', I discovered that there is a movie in pre-production in the UK:
Memoirs of Hadrian: 'In a daring adaptation of Marguerite Yourcenar's bestseller "Memoirs of Hadrian," John Boorman recreates the life of Roman emperor Hadrian which is written in the form of a letter from the aging emperor to his young successor, recounting the story of Hadrian's early political career in the second century A.D.'
