I don't want to hijack his riddle, but I asked for a next screenshot from him yesterday and he still hasn't posted, who knows when he'll be back.

I'll have to give you a hint myself then: it's an american sci-fi show that went from the tail end of the 70s to the beginning of the 80s.

a new screenshot from the series?

coming right up....


its small and blurry but a dead giveaway, and it's not Logans Run (nice old series that also aired in the netherlands, i don't know if we broadcasted the complet series but it was on dutch television.
So Logans Run is NOT the series .....

It is easy as pie .... "bidibidibidi bidibidibidibidibidi "

My guess is that it's Buck Rogers in the 25th century! I am especially fond of the main music theme of this short lived series.
