'Jurassic World: Dominion' has an important link to the first movie that you may overlook

• Warning: There are spoilers ahead for "Jurassic World: Dominion."
• The sequel's villain, Lewis Dodgson, appeared briefly in the first "Jurassic Park."

Laura Dern, Jeff Goldblum, Sam Neill, and BD Wong all reprise their "Jurassic Park" roles in "Jurassic World: Dominion," but you may have missed the fifth character from the 1993 movie who returns in the sequel.

Scott Campbell plays the film's villain, Biosyn CEO Lewis Dodgson, whose biotech company is housing a sanctuary for dinosaurs in the new movie.

If you thought that name sounded familiar it's because Dodgson was briefly in the 1993 film, but was played by a different actor, Cameron Thor.

In the original "Jurassic Park," Dodgson was the shady CEO who bribed Dennis Nedry (Wayne Knight) into stealing dino embryos from Jurassic Park in exchange for a huge payday.

Dodgson handed Nedy the film's famous Barbasol shaving can that doubled as a storage container. You may have noticed the can appear near the film's end. When Dodgson attempts to escape Biosyn, he grabs the original can but drops it before meeting an untimely demise.

Cameron Thor, now a registered sex offender, doesn't reprise the role

Although Universal hasn't officially said why Thor didn't reprise his role in this year's sequel, his recent criminal history may shed some light.

In 2014, Thor was arrested after being charged with multiple counts, including rape and kidnapping, in connection to providing acting lessons to a 13-year-old, according to The Hollywood Reporter. The actor pleaded not guilty, according to Variety.

Two years later, according to The Hollywood Reporter, Thor was convicted of "committing a lewd act against a minor" and was sentenced to six years in prison. Thor was released early in 2019 and is now a registered sex offender.

Insider reached out to reps at Universal but didn't immediately hear back.

Dodgson, the character Thor originated, is killed off by the end of "Jurassic World: Dominion" so it's more than likely we won't see the character again.

And for what it's worth, including Dodgson in "Dominion" just for a nod to the original was a bit of a letdown since there's no real addition to having him in the film.

"Jurassic World: Dominion," also starring Chris Pratt and DeWanda Wise, is in theaters now.
