The reduction effectively brings the subscription rate to £3.99 per month, which is still cheaper than a direct Disney+ subscription, which costs at least £5 per month if you split the £59.99 subscription cost over a year, or £5.99 per month if you choose a monthly payment cycle. Head to Disney+ to see its subscription rates.
Disney Plus launched in the UK on 24 March and is home to not only classic Disney films such as The Lion King, Bambi and The Jungle Book, but also feel-good favourites from Pixar, the Marvel Cinematic Universe and, Star Wars – including the original series The Mandalorian.
Oh, and don't forget your can stream nearly every episode of the Simpsons with the service.
If that's enough to whet your appetite, go to O2 now to get Disney Plus free for six months. Alternatively, if you want a taste of the Disney+ experience before signing onto an O2 contract, pick up a 7-day free Disney+ trial first.
