Memorial Day weekend typically sets the standard for summer box office sales, and the successful opening for “Thunderbolts*” is the start of an impressive holiday box office, experts say.

Marvel's 'Thunderbolts*' is opening on top of the domestic box office, while Ryan Coogler's "Sinners" is having another great hold.

Marvel Studios’ Thunderbolts* is striking box office gold to fire up the first weekend of summer movie season, at $75 million domestic and possibly $170 million globally.
