Uncle Buck (1989)

"I don't think I want to know a six-year-old who isn't a dreamer, or a sillyheart. And I sure don't want to know one who takes their student career seriously. I don't have a college degree. I don't even have a job. But I know a good kid when I see one. You so much as scowl at my niece, or any other kid in this school, and I hear about it, and I'm coming looking for you!"
When a sudden family crisis appears out of the blue, bachelor and party man Buck (John Candy) is to be called upon to help out with taking care of his brother's kids, of which he has very little recollection of.
Still, the good natured big brother takes a certain pride in being their official babysitter for the next few days, even though he was their absolute last choice.
But his positive and friendly attitude is soon about to be tested as the teenage daughter Tia (Jean Loisa Kelly) does her very best to make him feel "welcome".
Still, that is nothing compared to what Buck is about to cope with for the next couple of days, as he gets to know several of the towns favorite locals, everything from
the horny next door lady, the dead drunken birthday clown (with great dildo jokes), a preachy principal, an enraged girlfriend and of course Tia's sneaky boyfriend Bug!

One of my favorite childhood family comedies, and probably the second best John Hughes/John Candy movie, only beaten by the classic Planes, Trains and Automobiles (1987).
As a kid when I came home from school alone, John Candy was like my third uncle, or my favorite movie uncle. I loved his films and they always made me laugh.
Even though Uncle Buck might be a bit too cozy and cute in some parts, the whole nostalgic feel, and of course John Candy makes up for that.
Mike Starr is great in his very short, but memorable part as Pooter the birthday clown "I'm a god!".

The main theme used in the film by Hugh Harris is also pretty damn solid.
