A way to look at BMI Index values

Having had a recent conversation about how the BMI index can be inaccurate with someone, I have actually come up with a way to demonstrate it that most young people will be able to relate to Рthe Avengers and Loki. I used the intenet listed heights and weights of the actors that play these roles. This is what I found;
Robert Downey Jr. – Iron Man – BMI 25.8 – overweight
(yet his personal trainer considered him skinny, and I certainly do not see him as overweight)
Chris Evans – Captain America – BMI 26.3 – overweight
Mark Ruffalo – Bruce Banner – BMI 23.9 – normal range
(I believe this was before he lost weight for the role)
Chris Hemsworth – Thor – BMI 24.9 – normal
Scarlett Johansson – Black Widow – BMI 22.3 – normal
Jeremy Renner – Hawkeye – BMI 25.2 – normal
Paul Bettany – Vision – BMI 24.4 – normal
Tom Hiddleston – Loki – BMI 22.4 – normal
What this tells us: Since people look heavier on the screen, and none of these people appear heavy when we see them, we would expect them to all be normal or underweight range, excepting perhaps the very muscled Chris Hemsworth, yet they are normal to overweight. These are people who are paid to look and be lighter and more fit than the common person on the whole. These are people who pay personal trainers to keep them in the expected shapes for their careers. These people who look healthy, normal, not fat, well-muscled, and even underweight in some cases have BMI’s that say they are normal and overweight. BMI isn’t very realistic.
