Night at the Museum trilogy

So, we've got Lara, this total dreamer who—despite having the worst luck imaginable—is convinced he’s destined for greatness, right? Well, turns out his luck is pretty much non-existent even when he lands a job as a night guard at the museum.
But then things get absolutely wild during his shift! We're talking Roman gladiators and cowboys coming to life and picking up their historical beefs right there in the halls, plus you've got Rex the T-Rex, who basically serves as a terrifying reminder of why he's considered one of the most bloodthirsty beasts to ever walk the earth. In all this madness, the only guy Lara can actually turn to is Roosevelt (Robin Williams), who steps up to help him save the whole museum from falling apart.
