This weekend, Hollywood A-listers will be gearing up for the Oscars—that annual celebration of films that you thought were pretty good, but definitely not as good as that one indie flick starring that guy from that one show.

But before suiting up and strutting down the red carpet, actors Ben Affleck and Seth Rogen (of Daredevil and Green Hornet fame, respectively) will make a brief detour to D.C. in order to testify at two different Senate panels this week. Time reports that, on Wednesday, Rogen will be in town to testify before a Senate Appropriations subcommittee in a hearing on the economic impact of Alzheimer’s research in the U.S. Rogen is no stranger to philanthropy and advocacy—particularly in the field of Alzheimer’s research. In 2012, Rogen and his wife started the annual event, Hilarity for Charity, which has raised hundreds of thousands of dollars for the National Alzheimer’s Association.

And on the same day, Affleck will also be on the Hill testifying before the Senate Foreign Relations Committee in a hearing about the Democratic Republic of Congo. Affleck—who has a history of advocacy in the Congo, and founded the Eastern Congo Initiative—will discuss the country’s declining economic, development, and social status, and raise awareness of the country’s problems along with a panel of experts.

See, celebrities aren’t all like this guy.
