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.)
