Walking Trail

Marcus Callum was a corrupt InGen employee. He was mentioned in Jurassic Shark II: The Retribution and appears as one of the main villains in Jurassic Shark III: The Revolution. He is portrayed by Ian Aston. 

Jurassic Shark IIEdit

While Marcus never actually appears in the film, Simon leaves him a message on his phone, telling him and the other employees to withdraw from the walking trail. He adds that they will need to rebuild their forces if they wish to commence the final part of their plan, revolution. After this, he ends the message and runs off into the woods. 

Jurassic Shark IIIEdit

Marcus aids Simon in his final plan to wipe out the Shark Hunters and their allies, by sending groups of employees out to kill the group's members. Some time prior to the film's main events, Marcus helped kill many of the Shark Hunters, with Russell Griffin and Gabe Reynolds stepping out of the action and going into hiding. 

In June 2017, Simon deployed two ADM models - a Mako and Tiger Shark - with Marcus' help. The sharks went to the walking trail and attacked Owen Hawkins and Logan Shaw. Marcus assisted Simon during this time as they amassed the corrupt InGen employees to attack the town of Bradford, but unbeknownst to them, Owen was trying to reunite the Shark Hunters. During this time, he rescued an old friend, Billy Trenton, and they were joined by Keith Douglas - a corrupt InGen employee who defected to the Shark Hunters. Gabe would eventually set off to the walking trail to find the Bombshark, the employees' weapon of mass destruction. Marcus and many other employees went into the walking trail to ambush Gabe.
