Jake Gyllenhaal continues to grow out his long hair for his role as Prince Dastan in Prince of Persia: Sands Of Time, out 2009.

The 27-year-old actor led his family onto the Eurail (formerly Eurorail) in Paris, France on Friday morning — Reese Witherspoon and her two kids, Ava, 8, and Deacon, 4. Looks like the Gyllenhaal-Witherspoons are headed out for a weekend trip somewhere else in Europe!

Jake has been busy in London filming Prince of Persia with the support of Reese and the kids.
