Chiranjeevi is the father of lead actor Ram Charan. Chiranjeevi's cameo appearance during the first song number is made from a combination of new material and archive footage.
Dev Gill takes his shirt off and throws on the floor before picking the javelin (when he kills the lawyer). In the next shot when he picks the javelin his shirt is some 5 feet away.
When Dev Gill kills his father (in the car) you can see blood marks on his shirt. In the immediate shot when he enters his uncle's house the blood marks are not visible.
