It was never going to be easy for the new entrants this Box Office weekend. Both ‘The Kid Who Would Be King’ and ‘Serenity’ encountered different barriers to a successful opening in the run-up to their Friday release, and by Sunday night the two had grossed just a $12.1m combined total.

For Fox’s ‘The Kid’, its battle came against an audience generally uninterested in seeing the medieval lore on the big screen. Hollywood’s insistence on rehashing the legends of ‘King Arthur’ and ‘Robin Hood’ led to 2 flops in under 2 years, with ‘The Kid’ likely to follow in the footsteps of ‘King Arthur: Legend of the Sword’ and November’s ‘Robin Hood’ with its $7.2m opening.

Unlike the 2 however, ‘The Kid’ is a modern-day take, that sees young schoolchild Alex Elliot (Louis Ashbourne Serkis) find the Excalibur sword, create his own roundtable of knights, and go to battle with the evil Morgana (Rebecca Ferguson). Written and directed by ‘Attack the Block’s Joe Cornish, the film also stars Patrick Stewart, Angus Imrie, and Tom Taylor.

The sole silver lining remains its critical reception, slaying cinemagoers with its 85% on the Tomatometer and B+ on Cinemascore. This should provide ‘The Kidsome staying power in coming weeks, although its $59m budget truly requires a magical intervention to salvage any hopes of a profit.

Somehow, other new release, ‘Serenity’, performed even worse this weekend, earning just $4.8m in its first 3 days. Starring Matthew McConaughey and Anne Hathaway and directed by ‘Peaky Blinders’ writer Steven Knight, it sees Karen (Hathaway) approach ex-husband Baker Dill (McConaughey) with the instruction to murder Karen’s abusive husband Frank (Jason Clarke).

While murder’s on the agenda, no inquest is required for ‘Serenity’s Box Office death. If it wasn’t its poor critical reception (23% on RT), it was an audience who found it even worse (D+ on Cinemascore), which concluded in being the second worst wide opening of the year (behind ‘Replicants’), and Anne Hathaway’s worst opening in her career thus far. Someone call 999.

It wasn’t all doom and gloom, however. ‘Glass’ once again ended Sunday ahead of the pack with an impressive $18.9m, to bring its domestic total to $73.4m. Although $4m behind ‘Split’ at the same time in its run, we’re more confident of the film passing $100m stateside as each day passes. Its overseas numbers look healthy too; the Shyamalan-Blumhouse production sits on $89.1m internationally after adding an extra $23m this weekend.

More good news this weekend comes from WB, who round off the report with the news that ‘Aquaman’ has officially become the biggest DC movie of all time after overtaking ‘The Dark Knight Rises$1.084bn global gross with $1.09bn. Still in the top 3 domestically after 6 straight weekends, it earned $7.3m for a running domestic total of $316.6m. What’s that about superhero fatigue?
