'Drishyam 3' producer Kumar Mangat Pathak has sent legal notice to Akshaye Khanna after his exit. "He insisted he'd like to wear a wig. But...(director)...convinced him it wouldn't be practical...However, his chamchas...advised him he'd look smarter [with]...a wig," Pathak said. "His energy on set is absolutely toxic...If Akshaye does a solo film, it won't even collect ₹50 crore," he added.
