Rodney Rothman, co-director of Sony's hit animated film Spider-Man: Into the Spider-Verse, has revealed some of the alternate lines that were recorded by Marvel Comics legend Stan Lee for what would unfortunately prove to be his first posthumous cameo.In the film, Lee's character -- the shopkeeper of Stan's Collectibles -- speaks to Miles Morales about Spider-Man/Peter Parker's death, saying, "I'm going to miss him... We were friends, you know." According to Rothman, at least three alternate lines were recorded.RELATED: Spider-Man: Into the Spider-Verse Has a Hidden Daredevil Easter EggThe first was, "I can't believe it. I didn't think Spider-Man could die." The second line reads, "Why this stuff sells, I'll never know." Finally, the third, retroactively gut-wrenching line to be recorded was, "[I] always thought he'd outlive me."

Previously, Rothman revealed that "Stan's" follow-up remark of "it always fits, eventually" is one that also had an interesting history, with the original scripted line involving him telling Miles that the Spider-Man suit "never fits." However, the now-iconic line that made the final film came about during an impromptu follow-up take.

Lee passed away in November of 2018, one month before Into the Spider-Verse hit theaters. The film was ultimately dedicated to him, as well as Spider-Man co-creator Steve Ditko, who had also passed away earlier in the year.
