The Metro is reporting that Bill & Ted 3 will have a British feel according to an unnamed source. The anonymous source also said the following:
‘They’ll time-travel through London and meet historical figures, meaning the Queen and Winston Churchill could get cameos.’
Often info from unnamed sources turns out to be a red herring. Time will tell if this info is credible.
Update: Alex Winter has posted on his FB page that Bill & Ted 3 will not take place int he UK. Like I said, unnamed sources are not reliable.
