A cut-off clip is at Jean-Louis Bompoint's (the video's cinematographer) website.
Hothouseflowers.com interviewed lead singer Liam O'Maonlai about This Is It (Your Soul):
HF.com: Tell us about the video for the song.
L: We were in 'Top Of The Pops' and a guy, Michel Gondry, came into the dressing room. A pure Frenchman, thick French accent. Immediately, I'm cautious of people put upon us and their agenda but his personality and his sense of humour put me at ease. I thought 'We're gonna have fun with this guy!'
HF.com: Where was it filmed?
L: It was filmed in Dublin.
HF.com: And the overlaid effect - the refelctions of two situations in one view through shop windows and things?
L: ... Reflection.. it was a word he picked out and found it to be humorous - looking through shop windows. I can't remember most of the filming. I remember being in bed (the video begins with Liam scrambling in a bed in a street. This shot is overlaid on a shop window reflection with other band members looking at the bed in the reflection) and him telling me to wake up and then fall asleep!
