Not sure if it will be released in the UK or not, but the first Spy x Family anime film has been released in Southeast Asia. It apparently adapt the manga (which later made into a light novel) after the arc in Season 2 ended. I don't think you should watch the series first to follow with the storyline.

 

9.5/10 from me

thanks to the shit jokes!

 

I need to catch up on episodes, then I’ll watch the movie. I miss watching them!
