Considering, Endgame will have Spider-Man, The Lion King, Aladdin, Toy Story 4 trailers. Doesn't make sense.
Further End game is 3 hours which is way more than Hollywood films so ads and trailer will be less there to accomodate more shows.
Besides in India, it's no big deal, Bharat will be played with almost all films till it release. What I was talking about was in overseas.
