James Cameron and his brother are reportedly being hit with a titanic billion-dollar lawsuit, and it’s all due to e-cigarettes.

According to TMZ, the 61-year-old Avatar director is being roped into the suit after his brother, John David Cameron, sold goods to the founders of Safe Cig when he started working for the company in 2011.

Rather than using the Cameron name to the company’s advantage, however, the Safe Cig founders are claiming John ran the company into the ground, spending millions on booze, travel and even a bulletproof glass door for his office.

The litigants claim the brotherly duo intentionally crated the company after John defaulted on a loan received by James claiming interest for the business.

The Safe Cig founders are seeking $1 billion; neither Cameron brother has yet to comment on the lawsuit.
