Marvel is beginning to ramp up promotion ahead of the premiere of Avengers: Age of Ultron. If today's new trailer is any indication, the expected blockbuster should live up to all the hype.

The stacked line-up returns and with the addition of James Spader as the voice of Ultron, fans can expect a great cast. Avengers: Age of Ultron will be in theaters on May 1st.

Robert Downey Jr. recently teamed up with a charity to raise money for Julia's House, which a children's hospice facility. If you win the raffle you'll attend the premiere with him and get some other mighty nice perks as well.

Check out the trailer and let us know what you think.
