If we go by the past SINGER films Anna has always been given the "and" credit with the exception of "the Last Stand" so I'm expecting they will keep tradition with Anna having the "and" credit while Dinkelage will be given the "with" credit. Anna is an Oscar Winner and Golden Globe winner so her credits are stronger than Dinkelage. Yet, since Dinkelage is portraying the villain he will be given some stronger credit. Also his popularity with Game of Thrones (eventhough True Blood is more popular).
Also, Jennifer Lawrence will be given top billing of the female lead. She is an Oscar winner and a huge draw for audiences.
