The squad, to be captained by Ireland centre Brian O'Driscoll, incorporates players from all the Lions countries.
The North's starting XV will be announced next week, with South head coach Rod Macqueen having already named his line-up.
The World Cup-winning coach, who will lead Lions on their tour of New Zealand in the summer, admits he is thrilled to have such a star-studded group of internationals.
"The guys that have been named are world class and I am looking forward to working with such an outstanding group of players," said Woodward.
"The game promises to be a great spectacle. Both teams are fielding top-quality sides and I really hope that the rugby public and community get behind this game so that we are playing in front of a packed out Twickenham to raise as much money as possible for such a deserving cause."
