Our kids love this movie, and it’s difficult to find anything objectionable for any child aged 6+. This is a classic Cary Grant screwball comedy. Hepburn and Grant have electric chemistry.
(Disclaimer: We like classic movies because the material is generally suitable for the kids and it’s not dumbed down for them or us. Because much of the content is from a past era, some things need explanation. We prefer to use questionable content as teachable moments with which to reinforce our values.)
This is so funny, and has strong likable characters. Kate and Cary shines in this, and it just shows you how old movies can still make people laugh years after it was made. Plus, it's got a tamed leopard and a cool dog that everyone will want one for a pet. Did I also mention that it was funny. ( One mild caution: a drunk gardener.)
