See Arnold Digitally Fulfilling His Promise to 'Be Back'.

With Terminator Salvation getting dismal reviews and less-than-stellar box office, Sony Pictures has decided on the last-ditch effort of showing their entire Termi-hand, and they've released a new television spot that reveals the much talked about cameo by a young, digital Arnold Schwarzenegger head pasted on a bodybuilder Roland Kickinger's frame. If you haven't seen it yet, I think you'll be pretty impressed by how surprisingly convincing it looks. All those years of copy-and-pasting bosses' and teachers' heads onto naked bodies has finally fulfilled itself in a meaningful way.
