In about 25 years perhaps.
Well, the rights are currently with Belga Films, who announced in 2015 that a
Blake & Mortimer project was in the pipeline (this is different to the two previous attempts to mount an adaptation of
The Yellow 'M'); the script is said to be being developed by Jaco Van Dormael and Thomas Gunzig.
Interestingly, Belga Films have also recently announced that they have made a distribution deal for their output in some territories with Lionsgate - so, as I speculated above, there may still be some connection of that company to the
Blake & Mortimer screen adaptation rights...
