The floating open-air cinema launched with a sold-out screening of Jaws, where the audience were offered a free drink by Time Out's advertising partner Southern Comfort.
Time Out's film editor, Dave Calhoun, stated that the summer-long project intends to spark a "great content story" that can be "talked about to an audience even if they're not going to the event".
The unique experience allows the audience to enjoy sunset views of iconic landmarks and then enjoy a water- or London-themed film as it starts to get dark. Dave also discussed how the project's ambition is a way of embracing the audience's "love for the city through cinema at a unique event that they could only get through us".
City Cruises' managing director Karl Haughton hopes that "this will be a feature for future years" on the growing pop-up cinema scene in London.
Luckily, no sharks were seen throughout the duration of the journey.
