The film involves some scenes that are not recommended to children under 12.
I'm wondering about the emphasized word. According to the ABBYY Lingvo dictionary, one of its meaning is "to contain" something. I'd like to know if the word involves is relevant to this structure. If it isn't, then why? Is it just out of practical use or contradicts some lexical principles?

You have found a loose use of "involve"; I call it wrong. "Involve" when used to mean something like "include" most properly implies cause and effect: Playing tennis involves a lot of running back and forth. Not: A tennis match involves several games.
The effect of "involve" in your example, aside from its sounding like a slightly wrong word, is to make the statement weaker, vaguer. It is almost sarcastic.
By the way, those scenes would not be recommended "for" children. We recommend things "to" people when we tell them they should try them.
