Megastar Amitabh Bachchan, who recently did a cameo in actor Mohanlal's Malayalam film "Kandahar", says he admires the discipline in southern cinema.

"They may be in different language, but when the camera rolls we are all the same - professional, disciplined and nervous as hell! I have always admired the sense of discipline in the South," Amitabh wrote on his blog bigb.bigadda.com Saturday.
