Heartwarming / Back to the Future: The Musical

• One promotional trailer has Christopher Lloyd giving his blessing to the West End Doc Brown. When the latter recognizes him and goes onstage with excitement, Lloyd says, "he'll do."
• The Comic Relief sketch has Doc Brown saying that in 2020, the greatest minds came together to create life-saving vaccines.
• The musical gives Doc a fear of heights, which makes the famous clock tower scene even more heartwarming. He's so determined to get his best friend from the future back home that he faces his fears.
