Devin Ratray as Buzz McCallister
Buzz McCallister is the character of Kevin’s older brother. The common theme with older brothers is to be a bit of a bully and go out of their way to mess with their younger siblings. That is exactly the role played here, constantly standing in the way of Kevin.
Buzz plays it cool like he doesn’t care for his brother with his comment “he’s not that lucky,” when asked if he is worried. However, as we near the end of the movie, he reveals his true affectionate side for his younger brother as the family has their safe reunion.
