The Will and Jaden Smith starring After Earth - which may well be M. Night Shymalan's worst ever movie - should pull in between $35-40 million at the box-office this weekend, though it won't be enough to secure the top spot in its debut week, says Andrew Stewart at Variety.

Sony entrusted over $100 million in Shymalan and The Smiths to make the sci-fi action movie, though reviews have been woeful with one critic opining on whether it may be the worst film ever made. Though a $40 million haul would leave studio executives pretty pleased, failing to secure the top spot will be concerning. That should go to Universal's fabulous 'Fast and Furious 6' with takings of around $50 million. The latest movie in the action franchise is among the best reviewed mainstream movies of the year and should bring its 10-day total to a quite miraculous $175 million.

Elsewhere at the box-office, family flick 'Epic' should continue its good run and pull in $21 million to take its overall total to $21 million. The $100 million Fox film is close to recouping its budget and should shift plenty of DVDs and BluRays. Jj Abrams' Star Trek Into Darkness is expected to take $20.5 million while the badly received Hangover Part III is likely to drop out of the Top 5 entirely. Not the send-off that was promised.
