The lab technician says that there were 32 more seconds of Daniel Feeld's memories recorded on the first day than had been accounted for. In fact, at the end of the first episode, Daniel's "extra" memory lasts 47 seconds. The first 15 seconds (in which he remembers that he used to imagine that he was part of a story in a big book) were not shown in this episode.
The credits here and in the first episode of Karaoke misspell actor Yoshinori Yamamoto's name "Yashinori". This error is also found in the published script book of both series.
Goof: Daniel Feeld had said in Karaoke that he was raised in the Forest of "Nead" and even commented on "N-E-A-D" vs. "N-E-E-D." At the dance where he first meets Beth, however, the sign clearly says "Forest of Dean," the actual name of the place where Dennis Potter was raised.
When Cold Lazarus was shown in Israel, "Reality or Nothing" was subtitled in Hebrew as "Rak M'tzeeut," which means "Only Reality," and instead of RONs, the terrorists were ROMs.
