(Reuters) – The co-founder and former chief executive of Maker Studios, Danny Zappin, filed a lawsuit aimed at preventing a shareholder vote on a takeover offer from Walt Disney Co, the Wall Street Journal reported on Thursday. Zappin and three other former Maker executives asked a California court to issue a temporary restraining order to delay an April 15 vote by Maker shareholders, the Journal said. Disney agreed in March to buy Maker Studios, one of YouTubes largest networks, for $500 million. A Disney spokeswoman had no comment. (Reporting by Lisa Richwine. Editing by Andre Grenon)
