Possible Clues:

• Utter failure
• Tragedy a 'thesp' actor performing
• Event causing much damage
• Attach ropes badly ... tragic event
• Animal with a bad temper -- he creates disaster
• He's after a feline clutching a strip of leather -- disaster!
• OAP chatters about disaster
• Tiger, say, having a fit of bad temper -- he's a disaster!
• Phase (conclusion to Lear?) to act out
• Lion perhaps a pet? That leads to explosive disaster
