EXPLORE Pompeii, the ancient mummified city, in Lost Worlds: The Roman Empire — Grandeur and Decadence ( Sunday, 7.35pm, SBS), the final episode of this terrific series. Recent excavations reveal hedonistic signs of decay. In Rome, where circuses were the chief form of entertainment, elaborate spectacles were a regular event in a vain attempt to gain favour from whatever gods would listen to Roman needs. Runaway elephants were still a problem, as were fires in the wooden seats. Brilliant Australian actor Aaron Pedersen ( catch him in SBS’s doco- style The Circuit ) is a subject of Inside Australia ’ s My Brother Vinnie ( Wednesday, 8pm, SBS). This intimate observational doco captures his loving relationship with 34- year- old brother Vincent, who suffers from mild cerebral palsy and an intellectual disability. A behind- thescenes look at the brothers returning to their home town of Alice Springs. Strait Up: Stories From the Torres Strait — Marcy’s Playground ( Thursday, 7.30pm, SBS) is an irresistible look at a part of Australia few of us know. If you loved last year’s RAN ( remote area nurse), don’t miss this cross- platform program that is also training young indigenous filmmakers. Versailles Stories: Magical Nights ( Friday, 7.30pm, SBS) looks at the madness of contemporary art, culminating in a two- night extravaganza involving wallpaper, coloured transparencies and a giant disco ball.
