As Timmy in "Jurassic Park," little Joseph Mazzello held his own against a ticked-off T-Rex and a pair of nasty velociraptors.
But now, 20 years later, he's taking on an even nastier enemy: Cobra Command.
The actor, now 29, appears in this weekend's "G.I. Joe: Retaliation" as Mouse -- a sniper on a mission with Duke (Channing Tatum), Roadblock (The Rock), Lady Jaye (Adrianne Palicki) and Flint (D.J. Cotrona).
Check out a shot of him on set with Palicki and costar Ryan Hansen below:
For some, it may be surprising to see Joseph attached to a big name release again -- but he's been working steadily since 1996.
After graduating from USC's School of Cinematic Arts, Mazzello appeared in "The Social Network" and starred in HBO's miniseries "The Pacific." He also recently appeared on the fourth season of "Justified."
But what happened to the rest of the "Jurassic Park" cast? Check out our gallery above to find out!
See Mazzello in action this weekend in "G.I. Joe: Retaliation" -- and be sure to catch "Jurassic Park" in theaters when it's re-released in 3D on April 5.
