According to express.de the German Collateral premiere will take place in Cologne at the Cinedom cinema on September 1st.
The website also claims that Tom wanted to have the premiere taken place in Cologne rather than in Berlin. No word on his fellow co-stars, but director Michael Mann will be present. Tom will be signing autographs and posing for photos for 2 hours.
At 12am he will be attending a press conference only to arrive for the premiere at 6pm.

Too bad I live in Munich I have to throw in and too bad that the UK prem is on September 2nd cuz I’m coming back from London on August 20th. Nothing ever works out for me does it? *lol*
