Tele has posted the entire 7+ min interview that El Pais did with Keanu Reeves. The extended article that has already been posted came from this clip. It is in Spanish. Before they start talking to Keanu they are telling abut his arrival, walking around, and his interaction with the worker at the gas station, etc.
The actual interview with Kanu starts around the 4:30 mark. The beginning is the clip that has already been posted but it also shows the conversation that takes place after the discussion about the Oscars and gravity.
