‘Reservoir Dogs’ — REUNITED … Mr. Brown, Mr. White and Mr. Orange

Reservoir Dogs” stars Harvey Keitel and Tim Roth reunited with co-star/director Quentin Tarantino last night in France — and not one person was shot.

It was all for an award being given to Q.T. at the Lumiere Film Festival in Lyon … where both Keitel and Roth gave speeches during the presentation.

Last year was the 20th anniversary of “Dogs” … and the movie is widely considered one of the best independent films of all time.

It”s unclear if they were discussing the appropriate tipping amount.
