He turned 40 in 1987
Basically when his career was just pivoting from action star to blockbuster star.
But 40 is the beginning of the end for most Hollywood actors.
Many go from playing that "30 something", "youngish" character, to suddenly playing a suburban parent with teenage children or young adult children.
So he was on notice.
Somehow he pushed his career as an A Lister into 1994.
Last Action Hero, 1993, was the beginning of the end. It wasn't the movie people wanted.
1994 saw a rebound with True Lies, and people breathed a sigh of relief.
But Junior came out in 1994 as well.
Unlike Twins, this movie didn't have that comedy or feel good vibe. It was a weird trans mocking movie which has aged horribly.
Eraser, 1996, saw a near 50 year old still trying to play an action hero.
The way he runs as bullets fly looked like an old man.
He'd lost it.
Somehow Hollywood hadn't checked his age and thought that he was worth 25 million to appear in 1997's Batman & Robin, playing Mr Freeze.
That was 7 times what George Clooney got, who was hot property at the time.
After this flop, Hollywood was still taking a bet on the now 50+ actor.
He pocketed another 25 million for the 6th Day in 2000.
It was a huge flop.
Thankfully for him, this now box office liability was the only person who could play the Terminator.
He would pocket 29 million for Terminator 3. Thankfully the movie was a success.
2015, he would again play terminator, this time making only 15 million.
Not sure what he got for the last Terminator, but needless to say, the franchise has been his meal ticket.
