Cruise attended the red carpet screening with fiancee Katie Holmes, and spent time speaking to fans outside Leicester Square's Odeon cinema before giving interviews to attending journalists.
But he was left drenched by the unexpected attack planned by the film crew shooting footage for an upcoming British comedy show featuring practical jokes played on celebrities.
The visibly shocked movie star struggled to keep his cool as he stood with his face, hair and jacket soaked with water - and he could not refrain from repeatedly referring to the microphone-wielding interviewer as a "jerk".
Before the man was led away by cinema security staff, Cruise said to him, "That's incredibly rude. I'm here giving you an interview and you do that, it's incredibly rude."
A police spokesperson has confirmed four people have been arrested on suspicion of assault.
After drying himself off, a composed Cruise returned to spend a further hour mixing with his fans.20/06/2005 02:48
