15 month not responding to name often

SO! I have a newly 15 month old. He’s never really responded to his name .. we call him Brooks or Rook or Bubba and a lot of times he just doesn’t look back when you call for him .. now you’ll notice it a lot more if he’s watching a movie .. he’s been able to watch full movies since he was about 8 months old .. he’s just really into them (frozen , trolls , etc ) Maybe he’s just a selective listener .. he will look back after you say it quite a few times .. he started walking at 11 months , points , makes pretty ok eye contract but would prefer not to , laughs and smiles a lot , climbs everything , is obsessed with his two fox stuffed animals , but he also only say dada, baba, momma ... just babbling ... anyone else have a 15 month old who sounds like this ?

I’m mostly worried on why he won’t look back as much when we say his name ... here he is ! He’s also massive .. 33 inches and 28 pounds
