arnold spent years being super busy - governor + marriage.
Suddenly he has neither, his kids are grown... he's probably BORED. More $ than he could spend in ten lifetimes, just spending the days shopping and wandering around. Why not make movies and feel important again?
You talk like if he's the only rich celebrity around, that just woke up one day and found himself old with kids grown...
You see wealthy celebrities getting old everyday, Michael Douglas,Harrison Ford,Robert DeNiro,Al Pacino,Eastwood,etc all older than Arnold and look at their work in motion picture at older age.....
If Arnold cant do the Comando,Red heat,True lies etc type of roles anymore why ruin that legacy?
I hope that movie has an amazing story line cause he does look ridiculous in those scene, sorry.
He looks like the mentally challenged grandpa' of beto el recluta.
