Fan Expo Dallas has secured a T-Rex-sized guest for their April convention: Jeff Goldblum. He joins an already star-studded cast that includes Michael J. Fox, Jason Momoa and Felicia Day.

Goldblum was already a geek icon for his classic role as Ian Malcolm in Jurassic Park (a part he's revisiting in the upcoming Jurassic World: Fallen Kingdom), but more recently he shone as the Grandmaster in last year's Thor: Ragnarok.

In addition to a fan Q&A at the show, Goldblum will be on-hand to sign autographs and pose for photo ops (though keep in mind that those one-on-one opportunities almost always come with an extra charge not covered by your ticket into the event). This year also marks the 25th anniversary of the original Jurassic Park, so Fan Expo will have a replica Jurassic Park jeep on hand.

Fan Expo Dallas will take place at the Kay Bailey Hutchison Convention Center April 6-8. Passes to the event can be purchased at the Fan Expo website.
