No film in the US has spent this long at the top since Avatar in 2009 so this is kind of a big deal.
This weekend Panther takes $27 million which takes its total US gross to $605 million.
Coming in at number 2 this week, and the highest new film, is Tomb Raider, the new reboot following on from the rebooted games from a few years back.
Despite mainly positive reviews the film still only manages to gross half that of the Angelina Jolie movie from 2001.
The Alice Vikander version of the video game heroin takes $23.5 million on its opening weekend.
Faith based movie I Can Only Imagine is new at 3 and gets the highest per screen average on the charts and has far outstripped expectation, the film takes $17 million for the weekend.
Finishing off the top 5 is A Wrinkle in time at number 4 and sinking fast and Love, Simon which is new at number 5 this weekend.
