Hartley and Lawes have both come off the bench in England's opening two wins over Scotland and Ireland, and those performances have earned them recalls into the starting team by head coach Stuart Lancaster.
England may be topping the Six Nations table with their two victories, but Lancaster said that he had no qualms about changing a winning team.
"We thought long and hard about changing a team which did so well against Ireland," he commented. "But we believe that Dylan, Courtney and Manu [Tuilagi] are ready for the opportunity and allow us to vary our play, while the bench will add impact and energy as the game unfolds in the second half.
"The players are really looking forward to getting back to Twickenham; the atmosphere in the stadium is fantastic and hopefully the crowd can get behind us in what is sure to be a great challenge against a motivated and physical French team."
