Aidan Gallagher

Aidan Gallagher is one of those rare cases where "child actor" doesn't feel like a warning label. I first noticed him on Nicky, Ricky, Dicky & Dawn, where he held his own as Nicky Harper on a show packed with kid performers — genuinely charming, not cloying. But the moment that really locked him in for me was Number Five on The Umbrella Academy. Playing a time-traveling, ruthless assassin trapped in a 13-year-old's body is a genuinely tricky sell, and he pulls it off with this deadpan gravitas that most adults can't manage. Born in 2003, he's still only in his early twenties, and on top of acting he writes and releases his own music — which, honestly, good for him for not coasting on the Netflix fame. He's also a UNEP Goodwill Ambassador for environmental causes. The trajectory is interesting enough that I'll keep watching.
