Movie for 3 year old

[Birthdayboy2]

It's my LO's birthday in a few days, we're not seeing anyone as I'm pregnant but to make it a bit special we thought we'd do a "movie night" with a goodie bag and treats and snuggle up on the sofa. He's never watched more than 20 minutes of TV, so not sure if he could sit through a movie? Was hoping to find something under an hour long but no luck so far. Best option seems to be Paddington, is it suitable for a 3 year old?
Thank you for any recommendation!

Winnie the Pooh...favourite film from that age.

Lol oh dear, my DD who is 3 has watched Spider-Man: Into the Spiderverse (2 hours long, PG) 5 times in the last week and a half she's going through a bit of a phase

She has easily sat through films for a while, fan of all the Julia Donaldson shorts, Frozen 1&2, classic Delaney - particularly 101 Dalmatians, little mermaid and beauty and the beast. Also likes Wall-E and Up.
