Theroux sported a heavy beard and dressed in his trademark black as he posed beside several of the off road vehicles.
The actor was all smiles as he checked them out ahead of the race in Morocco.
"The good news is that was probably the most — I'm choosing my words really carefully — it was kind of the most gentle separation, in that there was no animosity," he said.
He added: "Again, neither one of us is dead, neither one of us is looking to throw hatchets at each other," he jokingly added. "It's more like, it's amicable. It's boring, but, you know, we respected each other enough that it was as painless as it could be."
However, he did admit that it had been tough to adjust to their new lives. He added: "It was heartbreaking, only in the sense that the friendship would not be the same, as far as just the day to day."
