Damon Lindelof -- the co-creator of "Lost" -- is finally issuing a formal apology for one of the biggest mistakes he ever made ... unfortunately, we're not talking about his show's finale.
It's all over a joke Lindelof cracked on his Twitter page yesterday in the wake of the Spider-Man on Broadway accident -- he wrote, "With great power, comes great respWAAAAAAAAARRRRRRRRRGGGGGHSMASHCRASHKATHUMP!!!!!"
Kinda funny -- but kinda inappropriate considering the accident may have ended the stuntman's career.
But today, Damon owned up to the situation -- tweeting, "I had no idea that the stuntman was so seriously injured. Bad taste. Honest regrets. And hoping for a speedy recovery."
Still waiting for an apology for not explaining the numbers ... the DHARMA initiative ... the polar bear .... the smoke monster ... Walt ... the frozen wheel ... the lighthouse ...
