The House of Hate (1918) paired Antonio [Moreno] with Pearl White, fresh from her tremendous, worldwide success in the serilas The Perils of Pauline, The Exploits of Elaine, and The Romance of Elaine. This new, twenty-chapter serial cast Antonio as a young scientist in love with the daughter of a munitions king. Each weekly episode followed the young lovers as they escaped the perils of « The Hooded Terror ».
Antonio went into immediately to work in fifteen episodes of yet another serial, The Iron Test (1918) , as a circus acrobat hounded by menacing « Red Mask. »
[…] In 1920, Albert Smith put Antonio through fifteen weekly episodes of more danger in the serial, The Invisible Hand. This was immediately followed by another fifteen-episode serial, The Veiled Mystery.
James R. Quirk, editor of Photoplay magazine, in his 1920 review, noted Antonio’s tremendous drawing power, declaring him « the king of serial actors, » superior to others because of his onscreen prowess as a romantic idol.
