@One illustration of this: Some people will cry buckets over a sentimental movie but rarely in real life, even under duress.

Interesting: I've got a project "loosely" titled " I Only Cry at the Movies".
It's in an early development stage but I've ALWAYS had this inkling of an idea about the secret power of film on emotions where in "real life" they are not apparent.
As always, GITS "gits" it out as far as allowing a writer to explore ideas!

Yup, that was SOME trailer, all right! Have to admit, the perky, "family film" interlude right there in the middle is what really did it for me.
