The Batman brought a grungey new take on DC's Dark Knight and reopened Gotham City for business, HBO's The Penguin is back to remind us all why we loved that movie so much. That episode 1 achieves that while expanding the world and turning the light of the Bat Signal onto Colin Farrell's Oz Cobb without Robert Pattinson's Bat is a hugely impressive start.

The Penguin has now kicked off on HBO, and the first episode of The Batman spin-off is a grisly return to the dark underworld of Gotham. It mostly focuses on Oz Cobb's new bid for power following Carmine Falcone's death, but there is a little subtle tease in there for fans of Matt Reeves' movie.

The Penguin's first episode contains references to wider Batman lore, but a specific one will pique the interest of the Caped Crusader's fanbase.
