Downey didn’t get into any drugs that messed with his appearance, whereas Lohan became a methhead and aged 20 years.
In Hollywood, where looks are everything, there’s no part that a pre-aged young person would be seriously considered.
True enough.
And not just drugs like meth.....Downey’s quite a good actor in truth. Lohan....meh, not so much. She was cute. Nowadays, she’s starting to look like she was rode hard and, well, you get my drift.
