"Looks like I picked the wrong week to quit amphetamines ..."

The right answer is:
Airplane! (1980)

Those who knew the right answer were:

• Burton Plastic:
"Looks like I picked the wrong week to quit amphetamines -is as my master tells me from American classic (although I'm not familiar with it) titled Airplane. It's a line told by Steve McCroskey a.k.a. Lloyd Bridges who seems to have made a carrier being a fool (like someone else we know but we will not mention any names will we?). This was apparently a horrible week for poor Steve as he also quit drinking and sniffing glue this same week.
Anyway... I believe hall of Fame is in order for my master ?"
• Bergþór Jónsson:
"Hljómar eins og Steven McCroskey (Lloyd Bridges) í Airplane! Hann var nýhættur öllu ef ég man rétt."
• Halldór E:
"Þetta er Lojjd Briddses úr Erplein !"

"They say there's just enough religion in the world to make men
hate one another but not enough to make them love"
