Absolutely one of my favorite movies of all time. Cary Grant's timing and crazy antics kept a smile on my face and laughing out loud throughout the whole movie. The actors, who played his aunts, were wonderful and outright, sweetly insane. You couldn't help but love them despite their poisoning lonely old men.
Arsenic and Old Lace is a feel-good movie with dark-edged comedy bringing it all together. Every time it is on, I watch it as if it is the first time, laughing all the way.
