"For an actor, there can never be a substitute, there is only one profession and that is acting. If you are once an actor, you will always be just an actor," the 31-year-old said here in an interview.
"The other things are hobbies, which support and teach an actor to go to the next level only to hold his own skill, that too of acting. I compose music only because it helped me to understand about diction, sur, rhythm, voice modulation, so many things," he added.
Neil, who will soon be seen in "3G" with Sonal Chauhan, also asserts looks should be last priority for an actor.
"This is not a character where she (Sonal) or I have to just look good. Looking good is the least that an actor should concentrate on. Cinema has this magic about it that whoever comes on the big screen tends to look good," Neil said.
Besides, "3G", Neil is also working on "Ishqeria", "Rum Pum Posshh" and "Dussehra".
