Actor and director Casey Affleck was at the State House on Tuesday to lobby for more legislation to protect animals. He joined House Speaker Robert A. DeLeo and State Representative Marjorie C. Decker for a nice portrait in DeLeo’s office. Casey will stay in town to serve as the creative adviser for the Independent Film Festival Boston. He’s expected to appear at opening-night festivities on Wednesday. . . . While one Affleck was advocating for animals, another announced his involvement in a campaign to fight poverty. Ben Affleck says he’ll live on $1.50 a day for five days as part of the Live Below the Line project, which aims to educate people about the poverty line. The week runs from April 29 to May 3. Ben’s Eastern Congo Initiative is working with the cause.
