Correction: Daniel Tammet 'Brainman' Documentary

June 7, 2010— -- Last week, "20/20" told you about a British man with Aspereger's Syndrome who is capable of some amazing feats of memory and learning.

In that report, we said we watched Daniel Tammet take on the Icelandic language on a visit to that country. In fact, Daniel's trip was recorded four years ago by a documentary team which licensed "20/20" the videotape from their film, "Brainman." ABC News should have cited the documentary and made clear when it was recorded. We apologize for the errors.
