Meh. He's got a good opening to deepen his career here with War and The Night Manager. He should focus here and not make the mistake DP did with XXX.
Also Hollywood is not so welcoming to South Asian or brown MEN as they are with brown women who can play exotic or femme fatale parts.
Work is work and he has the same chances anyone else may have, limiting yourself to only doing films in one country is extremely provincial and backwards, don't people in India watch films made in Hollywood? and know of actors from Hollywood. Why should India's talent be any less? Hollywood is a huge machine that has people working from every conceivable place in the world, there no body cares where you come from or where you go after work, they just want to make THE money.
