Welcome to the forum.
You need a cinema pass to watch any of the movies in the Movies section of the NOW TV app, which costs £9.99 pm. More detail here

If you've not had a cinema pass before you should be able to get a 14 day free trial - check your My Account > My Passes page to see if it offers you one

If if its something you're interested in subscribing to regularly then you might be interested to know you can buy vouchers for NOW TV from Game (online and emailed immediately or in-store), Argos, Currys and PC World which save some money. Prices are
Entertainment - 3 months - £15
Entertainment - 5 months - £25
Movies - 2 months - £15
Movies - 3 months - £25
Sky Sports Week Pass - £10
Some people also like to buy the NOW TV boxes with bundles of entertainment or movies vouchers when they come on offer in places like Currys, Argos and Amazon and again the vouchers in those can be used by existing customers.
