Almost every pre-millennium comedy plot would be ruined by the existence of mobile phones, which poses a real problem for reboot-crazed Hollywood execs.

Ryan Reynolds' solution? Get the characters so stoned that they can’t even work their keypad. At least, that seems to be the plan for his spoofy Home Alone spin-off.

Stoned Alone will centre around a 20-something space cowboy who misses the flight for his skiing holiday. He returns home, smokes too much weed and becomes convinced that thieves have broken into his house.

His paranoia is soon vindicated, setting a series of Macaulay Culkin-inspired traps and tribulations in motion.

Ryan Reynold will produce the movie while Hollywood newcomer Augustine Frizzell (Never Goin’ Back, Euphoria) is set to direct.

Hollywood has had mixed fortunes with stoner movies. For every Pineapple Express there's been a Your Highness. But don't worry, we've got you covered.
