Fede Alvarez has joined original director Doug Liman for reshoots on the troubled adaption of Patrick Ness’ Chaos Walking.

The big screen adaptation of Patrick Ness’ book Chaos Walking has not been going to plan. Lionsgate is spending in the region of $100m on the movie, which stars Daisy Ridley and Tom Holland. Doug Liman has been directing the film, which was due for release this year.

However, the original release date has been and gone, amidst reports of the film needing an awful lot of work following screenings of the cut thus far. As such, that work is being done now, with fresh photography underway. This isn’t a few reshoots, either. Much new material has been penned, and it’s going to take three weeks to get the new material in the metaphorical can, at a cost of some $15m extra.

Furthermore, Liman has asked for help. Whilst he’s directing the fresh material, he’s also called in Fede Alvarez, who directed Don’t Breathe, for help. Alvarez, according to a report at THR, is taking on a consulting role, both giving notes on the script, and helping to plot the extra footage.

The film will not now be released until 2020.
