It’s hard to believe that it’s been 22 years since Steven Spielberg’s Jurassic Park introduced the world to the danger of raptors and the foolhardiness of taking cover in porta-potties.

With the recent premiere of Jurassic World – which just broke the record for the biggest opening weekend in history – PEOPLE decided to find out what the terrified but plucky kids of the original movie are up to these days.

Ariana Richards and Joseph Mazzello – better known as Lex and Tim Murphy – starred in the classic dino film at a young age. Where they are now might surprise you.

Richards, 35, has made a name for herself as a artist, traveling around the world painting and promoting her work. Though she acknowledges that life after Jurassic has been much quieter, she admits she wouldn’t mind acting again.

“If some great role or project finds me, absolutely that could be a nice thing to do, for sure,” Richards tells PEOPLE.

However, that might be difficult to fit into her busy schedule. The Jurassic Park alum is currently living in South America promoting her art tour. On top of that, Richards announced to PEOPLE that she and her husband, Mark Bolton, are expecting their first child together.

Richards’ on-screen brother, Mazzello, 31, stuck with the film industry, going on to earn a degree in cinema and television from the University of Southern California. In fact, he got some help from director Spielberg.

“Steven wrote me a recommendation for USC to go to film school. Believe it or not, I got in,” Mazzello previously told PEOPLE. “He’s been there for me throughout my life whenever I really needed him.”

Besides Jurassic Park, the actor’s most prominent role came in 2010 when he played Facebook co-founder Dustin Moskovitz in The Social Network.

These days, he’s focusing his energy on the other side of the camera, directing and writing.

He made his directorial debut with a film called Undrafted. He also runs his own production company, JJM Productions.
