The clip Back to the future Part 5 from Back to the Future Part III (1990) with Christopher Lloyd, Mary Steenburgen
It's Clara! She's on the train!
She's in the cab! I'm going back for her!
Doc! We're going past 50! You'll never make it!
Then we'll have to take her back with us! Keep calling out the speed!
Clara, climb out here to me!
I don't know if I can!
You can do it!
Just don't look down!
Sixty miles an hour!
You're doing fine! Nice and steady!
Just a little further!
I can't! I'm scared!
Keep coming, Clara!
Come on! You're doing fine!
Come on! Nice and easy!
Don't look down! That's it! You're doing fine!
The red log is about to blow!
