Felix Gonzalez’s review published on Letterboxd :
UPA - The Jolly Frolics Collection
This is quite the departure from UPA's usual work. I'm hesitant to call it their best work because it's so stylistically different that it really stands in a class by itself, a true outlier. Also, I think I may actually prefer a few other shorts to this one. But comparisons aside, The Tell-Tale Heart is a bleak wonder. With designs inspired by Salvador Dali and static paintings in place of traditional animation, this feels more like an art piece than a studio cartoon. James Mason's feverish narration lends a dash of palpable madness that Poe himself would be proud of.
