My opinion, both as a mom and an elementary school teacher, is that kids learn negative behaviours
at home. My husband and I don't drink, smoke, do drugs, or swear. We don't lie to the kids and we treat them and each other with respect. I am quite sure that seeing a children's movie (with their parents by their side) will not turn them into drunks, drug addicts, or foul-mouthed terrors.
We really enjoyed the movie and so did the kids. We all like to cook together, so it was neat to see such an emphasis on cooking and good food instead of fame and fortune.
The OP's mention of seeing a bit of a cartoon man's behind was funny to me. My kids have seen me naked, each other naked, and definitely their baby sister naked many, many times. I'm not even sure what the OP is afraid will happen if children see behinds? We watch travel and nature shows on TV, so the kids have seen more than that on people living in natural environments. On a recent show, we discovered that the parks in Germany (at least in Munich) are "clothing optional." My kids both claim that they would love to play in the park naked

They both know that we all wear clothes because we have to, but that there is nothing wrong with the human body.
Since we don't drink, we've already had informal talks with the kids about alcohol and what it does to your brain and behaviour. They understood that when Linguini drank that stuff, it made him act crazy. I'd rather they know the effects instead of thinking it's some special, forbidden stuff that they want to find out about.
Walt Disney said that he didn't make movies for children; he made movies for families. Someone mentioned Curious George, which was a beautiful children's film. It was soft, from the colors to the story, and my son adores it. It was also pretty boring for Mom and Dad. It was not a family film, it was for small kids.
